CASA Tasks and Tools

Originally, CASA consisted of a collection of tools, combined in the so-called toolkit. The current toolkit still contains the full functionality of CASA, though most data reduction steps bundle a number of tools together to create the more familiar CASA tasks. That is to say, a task makes calls to a number of tools. 

While running CASA, you will have access to and be interacting with tasks, either indirectly by providing parameters to a task, or directly by running a task. Each task has a well defined purpose, and a number of associated parameters, the values of which are to be supplied by the user. 

The following subpages describe the CASA Tasks (also listed in the Global Task List) and CASA Tools (listed in the CASA Tool List) in more detail.
