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.
startup
