Loading CASA in your shell
On the UMD computers we use the "astroload" command to load CASA (in fact, it can load older versions as well). If astroload is not a recognized command, you will need to add "astromake" to your shell, e.g. put
to your .cshrc file (and the .sh variant if you use bash)
After this you could ask what versions of CASA are available:
astroload -i casa
and there might be quite a few. The first one is the default, viz.
but if you prefer another version, try
astroload -v 421 casa
The directory /astromake/opt/casa has all the root directories, the symlinks for our aliases, and a file called VERSIONS which versions we support.
