Description

This routine sets the name of the filter to be used when calFindFile() is next called. A value of "-" means that this field is not relevant for the query (i.e. that no filter was used).

This field corresponds to the filter parameter of the quizcaldb tool. It should be set to "-" for all queries of the Chandra calibration database.

The caldb module is not available by default; to use it in a S-Lang program, it must be loaded using the S-Lang require() function:

  require("caldb");
