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.
