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
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
