# Dual Grating MOS Flat Fields
#
# Sequence of Flat Field Spectra for MOS masks
#
# This script does a single flat of each combo
#
# Exposure times are reduced compared to long-slit flats
# because MOS masks typically use broaders slits for observing
# at the outer parts of the FoV, and to avoid saturation in
# the larger alignment star holes (biggest problem)
