NAME
    standard -- Add standard stars to sensitivity file
 

USAGE
    standard input [records] output
 

PARAMETERS

    input
        List of input standard star spectra or root names if  using  the
        record  number  extension  format.   All  spectra  of  the  same
        aperture must be of the same  standard  star.   In  beam  switch
        mode  or when the same star parameter is set all spectra must be
        of  the  same  standard  star  regardless  of  aperture  number.
        Normally  the  spectra  will  not be extinction corrected but if
        they are then the extinction file should also be given  and  the
        same extinction file should be used with sensfunc.
