Frequently Asked Questions
Welcome! We look forward to having you at the 2012 CARMA summer school. Please post your itinerary on the Wiki soon. 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.
Below are frequently asked questions and answers:
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, June 17th?
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 (20miles 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 6/17 or departing after 6/24 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 can have breakfast in the OVRO kitchen or choose to head 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, June 18th?
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 resume 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. 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.
If you have any additional questions, please don’t hesitate to contact Mary at email@example.com.
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.
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.
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 (June 23). 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.
Use this wiki table 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

You are strongly encouraged to bring your own laptop since a limited number of desktops will be available for student use. Wireless access will be available; if you require a cable ethernet connection please let Marc Pound know. We will have a switch with 6 ports and 6 ethernet cables. If more than six people need cable ethernet, you'll have to share!
MIRIAD is the data reduction and analysis environment. You should try to install it before arriving at the school. It can be installed on Linux and Mac. A new release, dubbed school12 will be released shortly, but a beta version is available already. See the Miriad wiki page for details on obtaining and installing; if you have questions contact Peter Teuben (firstname.lastname@example.org), who is more than happy to help.
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.
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
From the GUEST network, there are two printers available:
clrcarma.mmarray.org -- color printer bwcarma.mmarray.org -- black and white printer
The main account for observers is obs; you can work on machines cedarflat or cedarflat4:
ssh -X email@example.com
ssh -X firstname.lastname@example.org
The password will be given out at the school.
Scratch Disk Space
Summer School disk space is /misc/scratch/summerschool. You may create your own subdirectory for reducing data or whatever.
Note: files in /misc/scratch/summerschool will be deleted after 90 days.
Planning Your Observing Project
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 most compact E configuration, with an angular resolution ~10 arcsec at 100 GHz, and ~4-5 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.
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 230 GHz system will depend strongly on weather. 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 paired up on observing projects. Project ideas will be discussed on the first day of the school with the first observation intended for that night.
Once the projects have been decided, each group must insert the project information via the Summer School proposal web page. The login/password will be given at the school.
