# Slitless Blue Grating Flats
#
# These are used to make general pixel-to-pixel flat fields
# for the blue-only grating spectroscopy modes.
#
# Takes 5 slitless flats in a Clear filter followed
# by 5 slitless flats through the UG5 filter to boost
# UV light.
#
# For dual-channel flats, use grpixflat.cal
