How should I create and use my own Observatories table when an observatory is not known to CASA?

Authors list

You can create your own copy of the Observatories table by taking it from the "<CASA-distro>/data/geodetic" directory in your CASA installation and then editing your copy with the browsetable task in CASA. Once you have your own copy, e.g. in the directory "/home/myself/mydir", you should create or (if it exists) edit the file "~/.casarc" and add the line

measures.observatory.directory: /home/myself/mydir

This will tell CASA to pick up your copy of the Observatories table instead of the default.

Note: The table must still be named "Observatories".
