rgssources (rgssources-6.3.3) [xmmsas_20230412_1735-21.0.0]

Simplest case.

After the initial source list has been made, the user will generally want to add some source positions of his/her own. The simplest call to do this is:

  setenv SAS_CCF <the .cif file> [if it hasn't already been done, of course.
From now on I'll assume that SAS_CCF has been set - it is always necessary.]

  rgssources srclist=<previous rgs source list> addusersource=yes
ra=<user src ra> dec=<user src dec>


  1. It is unnecessary to set the parameter filemode=modify since this is the default value.
  2. It is unnecessary with this call to supply an attitude history file.
  3. It is unnecessary with this call to set the environment variable SAS_ODF.
  4. If you addusersource but forget the ra and/or dec parameters, the task will issue a warning.
  5. The pointing and prime source remain unchanged by default.
  6. It is a good idea to specify a label as well for your source via the parameter label. Reason: the default value is 'USER'. If you try to add another source using again the default label value, the task will not allow this because LABEL values must be unique.
  7. Parameter enablefilter if set will not at present prevent you adding an out-of-FOV source to the source list; however it will enable the task to generate a warning after the fact, and the out-of-FOV sources are flagged as it is in the resultant source list.
