Installing CASA

See the CASA Primer.

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.
