Installing CASA
See the CASA Primer for installation instructions for common OSs.
Installing CASA on Ubuntu
The following method worked for Ubuntu 9.04 (Jaunty).
- Download the tarball appropriate for your Linux distribution (from https://svn.cv.nrao.edu/casa/linux_distro/).
- Install to /usr/local/bin/CASA (or substitute your own directory).
sudo mkdir /usr/local/bin/CASA
sudo mv casapy-24.0.8115-001-64b.tar.gz /usr/local/bin/CASA # this is for 64-bit installation; substitute the appropriate tarball here
cd /usr/local/bin/CASA
sudo tar zxvf casapy-30.0.9860-001-64b.tar.gz
- Add the following environment variable to your .bashrc (or the equivalent command for your preferred shell startup script).
export PATH=$PATH:/usr/local/bin/CASA/casapy-30.0.9860-001-64b
- Test it out!
source ~/.bashrc # or open a new terminal
casapy
Starting CASA
Once installed, you can start CASA using the command "casapy"
## From a UNIX shell prompt
casapy
Note that, by convention, UNIX-level commands will be commented out so to facilitate parsing these pages into CASA scripts.
Listing Available Commands and Tools
# From within CASA
tasklist()
A more exhaustive summary can be obtained as follows.
taskhelp
Some commands are hidden away as methods under various objects. For example, to take a look at options under the imager object
help im
Notice that the method mem appears here, under help, but not under tasklist.
Getting Help on a Command
Let's get some exhaustive help on clean.
# From within CASA
help clean
This method is OK, and perhaps the following method is better.
# From within CASA
pdoc clean
Additional Tips
- When you started CASA, it gave you a lot of useful information. But now you've been mucking around for a while, and that info is lost. How do you get it back? Just rerun the startup screen.
