[POINT\]SET Item Value1 [Value2]
Set some selection criterium. Possible items are
ELEVATION Elmin Elmax :
specify valid elevation range (default 5 90, in degrees)
RMS rmsmax :
specify maximum standard deviation (from gauss fit) for the
measured pointing errors.
Optical pointing data has measured pointing errors with standard
deviation set to 0, so that SET RMS although meaningfull only for RADIO
or INTER data, can also be used transparently.
As for comands IGNORE, INCLUDE and REJECT, selection criteria
specified by the SET command will be considered for the next PLOT and
FIT commands. However, contrary to commands IGNORE, INCLUDE and REJECT,
the criteria will not be reset by any READ or FILE command.
