# Based on measured angle-dependent transmission for SST camera window
# (Durham window Run3) for the wavelength range 300 - 750 nm.
# Values >750 nm have been linearly extrapolated. Further measurements are
# planned to extend the measured wavelength range, which will be used as input
# to future simtelarray productions.
# Weighted average over angles of incidence on camera with distribution
# obtained from ROBAST ray-tracing, by Akira Okumura 2021-08-25.
# Prepared by Jason Watson 2022-05-12.
# Values below 300 nm based on transmission curve of Borofloat33
# (for 1 mm thickness at 50 deg incidence angle, scaled to match at 300 nm, KB 2022-05-27).
