Frequently Asked Questions

An FAQ written by Mary Daniel is here.

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, with Enterprise rental cars available. See here for details.

Detailed driving directions to OVRO and CARMA from Los Angeles, Reno, and Las Vegas are here.

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 Nelson Campground; its entrance is about 1 mile west of the entrance to the CARMA site on the opposite side of the road from CARMA.

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 start from the Glacier Lodge trailhead at about 9 am, 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. Last year some of us pushed on farther, to Sam Mack Meadow, but were turned back by a thundershower. Some photos from last year's hike are here.

Shared Rides

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

Computers

You are encouraged to bring your own laptop; a few 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. Sorry, we don't support cygwin. See the Miriad wiki page for details on installing; if you have questions contact Peter Teuben (teuben@astro.umd.edu).

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
  • 54 Mbps microwave link between Cedar Flat and OVRO

The wireless ESSID at Cedar Flat is GUEST

Logging in

The main account for observers is obs

  • To log in to Cedar Flat computers from outside you must first log in to the firewall:

ssh -X obs@ssh.mmarray.org

Then hs will log you into the high site.

Chat

We have an AIM chatroom used by observers and staff: carma

Printing

Printing from the GUEST network: there are two printers clrcarma.mmarray.org and bwcarma.mmarray.org. The first is a color printer, the second is black and whitel

Scratch Space and Example Data

Summer School space is /opt/summerschoolscratch. You may create your own subdirectory for reducing data or whatever.

cd /opt/summerschoolscratch

mkdir yourname

Example Data

The NGC593 data which we will reduce together have been copied to

/opt/summerschoolscratch/cs053.NGC595.1.mir/

These data are about 1.7 GB. If you are working on your laptop, you can copy these data with

scp -rp obs@ssh.mmarray.org:/opt/summerschoolscratch/cs053.NGC595.1.mir /home/you/

The obs password is written on the board. NOTE: This examples copies to your home directory. Change /home/you to wherever you want.

Alternatively, you can download these data as a gzipped tar file directly from the CARMA Archive: cs053.NGC595.1.miriad.tar.gz

The Memo

As in previous years, the class with author a CARMA Memo with the results of your observations. I have created a master LaTeX file in /opt/summerscratch/memo/school2010_master.tex. 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!

I have put an example you may follow in /opt/summerschoolscratch/memo/mpound. Once you have added your text and figures, you should do

latex school2010_master.tex

dvipdf school2010_master.dvi

evince school2010_master.pdf

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

Example memos from previous years :

Planning Your Observing Project

The CARMA telescope is designed as an aperture synthesis telescope. There are two receiver bands: 3 mm and 1 mm. 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 15 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. 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. 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.
