This section is dedicated to a topic not of common interest, and therefore just serves as a container for the procedure developed to manage calibrators for ESO.
The secondary catalog holding calibrators submitted by the PIs of ESO programmes is CAL.xdr. To add calibrators, use the compile_cal procedure, and then update_cat to add the entries to the catalog. Using write_calvin, a list of calibrators can be written in the format used by the CalVin database.
