(FLUX CALIBRATION)
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.
