# Slitless Grating Flats
#
# These are used to make general pixel-to-pixel flat fields
# for the grating spectroscopy modes.
#
# Takes red and blue slitless flats in dual mode. A
# second set uses the UG5 filter in the blue to boost
# UV light.
#
# If using red-only or blue-only mode, use grpixflat_r.cal
# and grpixflat_b.cal, respectively.
