Welcome! We look forward to having you at the 2014 CARMA summer school. Please post your itinerary on the Wiki soon in the Itineraries & Shared Rides section. Doing so serves as confirmation for us to know you will be attending summer school and that you have secured both air and land transportation to the school.

Q1: Are there any detailed maps of how to get to the CARMA site from local airports, or from the CARMA site to OVRO (location of the dorms and cottage)?
A1: Directions/Maps to CARMA are on the Wiki under “Air and Land Directions to CARMA.” Click on “Detailed driving directions.” Select the directions needed. Also included is information on markets, gas stations, how to avoid getting a speeding ticket, photos of road signs, and other useful items posted by Marc Pound, school staff member.

Q2: Is dinner provided on Sunday, August 3rd?
A2: Spaghetti makings will be provided for all to enjoy (with you as the cook) Sunday evening at the CARMA control building. Other options are for you to bring food for Sunday night dinner, or make arrangements to find a place to eat. There are a few restaurants in Big Pine (the nearest town), and many more in Bishop (20 miles to the north).

Q3: I am camping. Where do I go to check in and get directions to the campgrounds?
A3: Upon arrival to the CARMA site, please check in at the CARMA control building for directions to the campgrounds. Also, email Mary if you will be arriving to CARMA before August 3 departing after August 10 so we know if we need to request accommodations for additional days.

Q4: I do not have land transportation yet. What are my options?
A4: Every student is responsible for providing his/her own air and land transportation. Option 1: Reserve a rental car. If you are renting a car and have space for additional passengers, please post how many passengers you would be willing to take so students can contact you. Option 2: Post your itinerary to the Wiki along with the request that you need a ride. We encourage students to share rides/carpool when possible.

Q5: What happens if I miss my shared car ride due to a flight delay?
A5: Emergency Back-up Transportation Plan: In the event that your flight is delayed and you miss your ride or something else happens to delay your arrival, please call the CARMA control building at (760) 938-2075 ext 181 to notify us of what has happened. Then, you will need to rent a car at the airport and drive to the CARMA site.

Q6: Where do I go for meals?
A6: If you are staying in an OVRO dorm room (in the valley), than you may have breakfast in the OVRO kitchen or choose to drive up to the Control Building. If you choose this option, you will need to plan for a 25 minute drive to the Control Building for an 8 am class Monday morning. (Classes will begin at 9 am thereafter.) If you are camping, you will want to have breakfast in the Control Building, where classes are held. Breakfast takes place between 7 and 8 am each day. Lunch and dinner will always take place in the control building.

Q7: Where should I go on the first day of class, August 4th?
A7: To the CARMA control building.

Q8: What time should I show up on the first day of class?
A8: 8 am. Again, classes will begin at 9 am from Tuesday on.

Q9: How do I pay for my accommodations and how do I know how much to pay?
A9: Mary will be sending an email communicating information about your lodging fees. It's estimated that the fee will be $40/day. Unless you are from an institution that is a CARMA affiliate (in which case your institution will be invoiced), you will need to bring exact payment in the form of cash or check with you to summer school. Fees will be collected once there. Note: Credit cards will not be accepted. Q10: Can I stay at CARMA after the school is over? A10: Possibly. If you'd like to stay at CARMA (as an official observer) after the school is over, please let Nikolaus (volgenau@ovro.caltech.edu) or one of the other instructors know. If you have any additional questions, please don’t hesitate to contact Mary at mary@ovro.caltech.edu. ## Travel Arrangements #### Air and Land Directions to CARMA For travel by air there are a number of options - Las Vegas; Los Angeles Area: LAX, Burbank, Ontario; Reno; Inyokern, and Mammoth Lakes. Most of these require a 4 to 5 hour drive to get to CARMA from the airport. The exceptions are Inyokern (airport code IYK) and Mammoth Lakes (airport code MMH) which are small regional airports near the Owens Valley. Only United flies to IYK (via LAX) and there are 2 flights a day. From IYK, it is about a 2 hour drive to CARMA (rental cars from Avis and Dollar available). Mammoth Lakes Airport is one hour north of OVRO and also has a few flights per day from LAX on HorizonAir and United, with Enterprise and Hertz rental cars available. See here for details. Detailed driving directions to OVRO and CARMA from Los Angeles, Reno, and Las Vegas are here. Maps: Google CarmaMap (a collaborative map maintained by some of us). Green placemarks are the CARMA buildings, yellow is the Ferguson Campground, blue are antenna stations. #### What To Bring If You Are Camping Since all meals will be at the control building, the only essential camping equipment is a sleeping bag and a mat. The sleeping bag need not be very warm, since nighttime temperatures will be above freezing. Students who prefer to have a tent to themselves should plan on bringing a tent. Tents will be provided for those who don't mind sharing. We'll do a poll for who needs what, once the accommodation choices are settled. The campground reserved for the School is Ferguson Campground; its entrance is about 1 mile west of the entrance to the CARMA site on the opposite side of the road from CARMA, at the sign that says Cedar Flat Group Camp. Follow signs to Ferguson. When you arrive, check in at the CARMA Control Building to let the observers know you have arrived, to pick up any gear you have reserved and to get directions to the campsite. #### Other Things You May Want To Bring Flashlight, bug spray, plastic coffee mug, sunglasses, windbreaker, hat with brim (for sun), sweater, rainjacket, water bottle, binoculars for star gazing/ birdwatching, camera, and good walking shoes. #### The Hike Our traditional post-summerschool hike is to Second Lake, in the Sierras above Big Pine. We plan to start from the Glacier Lodge trailhead at 9 am on Saturday (August 9). We should reach the lake about noon and get back to the cars by about 3:30 pm -- making it possible to return to Pasadena, Berkeley, or Las Vegas late that night. The hike is about 10 miles round trip with 2500 feet of elevation gain. The past 2 years some of us have pushed on farther, toward the Palisade Glacier; both times we reached Sam Mack Meadow but soon were turned back by thundershowers. ### Itineraries & Shared Rides Use this wiki table to help us plan accomodation and meals, and to coordinate shared rides. Give your name, your flight details, how many you can accomodate, and special notes such as whether you will be toting camping gear. For help on editting wiki tables, see this page Gender will be used to match up shared dorm/tent accomodations. Also please let us know any dietary restrictions since CARMA is providing most of your meals Participant Travel Information Name Gender Airport Arrival Day/Flight/Time Departure Day/Flight/Time Driving?

Wireless access will be available, as will wired ethernet. ### MIRIAD Miriad is the data reduction and analysis environment for CARMA. You should install it before arriving at the school. It can be installed on Linux and Mac. An new release, dubbed school14 is available. See the Miriad wiki page for details on obtaining and installing this; if you have questions contact Peter Teuben (teuben@astro.umd.edu), who is more than happy to help. Once installed, there are small sanity tests you should run to verify it is all working. Note: we will not be devoting any time during the school to MIRIAD installation issues, as we must concentrate on interferometry. Please make every effort to get it installed before you arrive. If you cannot get MIRIAD installed on your machine, you can log in to the available desktops from your laptop to reduce data. During the school Peter is available on gchat (user: teuben) to assist with MIRIAD problems. ### Electricity Electricity will be supplied at 120V, 60 Hz, using outlets accepting "American-style" parallel flat-pronged plugs. ### Network Info, Logging in, Directories etc. CARMA has two networks, public and private: • public - accessible to outside world (mmarray.org == ovro.caltech.edu), located primarily in the valley at OVRO • private – not accessible outside OVRO (carma.pvt), located entirely at Cedar Flat • There is a 54 Mbps microwave link between Cedar Flat and OVRO The wireless ESSID at Cedar Flat is GUEST. Note this ESSID is not broadcast. You should never need to log in to any of the valley computers from the high site. Direct ssh/scp to your home machine is possible from the GUEST network. ##### Printing From the GUEST network, there are two printers available: clrcarma.mmarray.org -- color printer bwcarma.mmarray.org -- black and white printer  Instructions for adding these printers to your Mac are here. ##### Logging in The main account for observers is obs. Any work you will not be doing on your own laptop, e.g.data reduction,should be done on s3.carma.pvt: ssh -Y obs@s3.carma.pvt The password is the obs password on the white board. #### Scratch Disk Space Summer School disk space is /opt/summerschoolscratch mounted on the computer s3.carma.pvt. You may create your own subdirectory for reducing data or whatever. cd /opt/summerschoolscratch mkdir yourname Copy your data from the system area to your own area: cp -pr /opt/sdp/sciencedata/yourproject.yourobsblock.mir yourname cd yourname Note: files in /opt/summerschoolscratch will be deleted after 90 days. #### Copying data to your laptop Many of you will be reducing data on your own laptop MIRIAD installation. When your observing is done, you can secure copy your data directly from sdp.carma.pvt: scp -pr obs@sdp.carma.pvt:/opt/sdp/sciencedata/yourproject.yourobsblock.mir . (note that final period is required!) ## Planning Your Observing Project Most students arrive with an idea of something they would like to observe while at the School. On the first day of school, we will discuss these ideas as a group and decide which have the most chance of success. We will encourage students to form small groups to plan, execute, reduce, analyze, and present their observations. We realize some of you may be completely new to interferometry and not have a specific idea about what to observe. That's ok, you can join someone else's group or the instructors can select a good target for you. ### About the Instrument The CARMA telescope is designed as an aperture synthesis telescope, typically operating as two independent subarrays of 15 and 8 antennas, respectively. In the "Science 1" subarray, there are two receiver bands, 3 mm and 1 mm, and the spectral line correlator described here. A basic aperture synthesis observation makes an image the size of the primary beam (λ/D ~1 arcmin at 100 GHz; 0.5 arcmin at 230 GHz) with a resolution corresponding to the maximum separations of the antennas. During the Summer School, CARMA will be in the compact E configuration, with an angular resolution ~10 arcsec at 100 GHz, and ~4 arcsec at 230 GHz. The "Science 2" subarray of eight 3.5m antennas will be available for continuum-only projects at 30 GHz (primary beam ~ 11 arcmin; resolution ~2 arcmin) and 90 GHz (primary beam ~3.6 arcmin; resolution ~40 arcsec). The Sci2 correlator produces 7 GHz of continuum data. ### Guidelines for your Project Your observing project should be achievable in a 3-4 hours time. Detection experiments are discouraged since we want you to get some actual data to play with. Availability of the 1mm system will depend strongly on weather, so we cannot guarantee 1 mm projects will be scheduled. Project ideas will be discussed on the first day of the school with the first observation intended for that night. You should be ready with some basic information about your selected target: • What kind of source is it? (galaxy, protostar, planet, etc) • What is it's right ascension and declination? • What frequency do you want to observe at? • Which subarray are you using? • Are you doing spectral line or continuum or both? • How bright is your source (Jy or K)? • What is the angular size of your source? • If spectral line, what is it's LSR velocity? • If spectral line, what is the expected line width? In order for the observing schedule to accomodate for all selected projects and to allow for make-up time in case of poor weather or unforseened circumstances, it is likely that some students will be grouped on observing projects. Once the projects have been decided, each group must insert the project information via Fast Track proposal system (Link below in LInks section) ## Proposed Agenda ## Updated Observing Schedule ## Missing baselines in spectral band 3 This card was replaced on Wednesday afternoon and the band is fully functional again Due to a bad correlator card, these baselines are missing from all spectral line band 3 data regardless of bandwidth mode until the card is replaced. The wideband correlator data (Sci2) are not affected. * Cross: Baseline 1- 7 * Cross: Baseline 1- 8 * Cross: Baseline 1- 9 * Cross: Baseline 1-10 * Cross: Baseline 2- 7 * Cross: Baseline 2- 8 * Cross: Baseline 2- 9 * Cross: Baseline 2-10 * Cross: Baseline 3- 7 * Cross: Baseline 3- 8 * Cross: Baseline 3- 9 * Cross: Baseline 3-10 * Cross: Baseline 4- 7 * Cross: Baseline 4- 8 * Cross: Baseline 4- 9 * Cross: Baseline 4-10  ## Lectures and Handouts and Useful Links ### Lectures We will attempt to broadcast the lectures live on the The CARMA Summer School Youtube channel. The live stream is under the Live Events tab; the broadcast lectures should be saved under the Videos tab.

## The CARMA Memo You Will Write

Results from student projects from previous Summer Schools are published in CARMA Memos, which are available at http://www.mmarray.org/memos/ .

Example memos from previous years : 2013, 2012, 2011, 2010 , 2009 , 2008 , 2007

As in previous years, the class will author a CARMA Memo with the results of your observations. We have created a master LaTeX file in /opt/summerschoolscratch/memo/school2014_master.tex. (Log in to s3.carma.pvt using instructions above) You should include your writeup in this file using the LateX \include command. There are more detailed instructions on the file itself. The easiest thing is to put all your text and figures in a subdirectory, e.g. /opt/summerschoolscratch/memo/yourname. Please use the latex \ref and \label commands to indicate figures and tables so Marc doesn't have to go through and renumber all the figures and tables! Also please use bibtex format for your references, putting them in school2014_master.bbl, and refer to them with \cite in the text. ADS can generate bibtex entries for your references for you automatically.

We have put an example you may follow in /opt/summerschoolscratch/memo/example. Once you have created your text, figures, and references, you should add a line to school2014_master.tex to include your file \input you/yourfile.tex and then do

pdflatex school2014_master.tex

bibtex school2014_master.aux

pdflatex school2014_master.tex

evince school2014_master.pdf

and fix any errors. There is no page limit, include as much text and as many figures as you wish.

## Photos: Picasa Web Albums
