SET SPIDX

            CLIC\SET SPIDX name value [frequency] [date] [/RESET]

        Enters `value' as the spectral index of source `name'.

        The flux of one or several reference sources must be given to CLIC as an
        input to command SOLVE SPIDX (which derives the antenna efficiencies and
        the  spectral indexes of the other objects).  If the spectral index of a
        source is entered by SET SPIDX, this source will be a reference  source.
        After  "SET  SPIDX name *", source `name' will not be a reference source
        any more. Its spectral index may then be re-determined by  a  subsequent
        SOLVE SPIDX command.

        Use command SHOW SPIDX to list the spectral indexes known to the current
        CLIC session. The reference sources are listed with  a  "FIXED"  keyword
        (their  spectral  index  is  fixed),  while the flux determined by SOLVE
        SPIDX are listed as "FREE".

        One may optionally enter a frequency (in GHz) and a date  (jj-mmm-yyyy).
        The  frequencies  and  dates are checked in that case by SOLVE SPIDX and
        STORE SPIDX. Matching is within 1 GHz for frequencies  and  1  week  for
        dates.

        If  /RESET  is given, all entries with the given source name are deleted
        from the flux list. SET SPIDX ALL /RESET will empty the  spectral  index
        list.
