# this file was taken from the logbook (https://www.fact-project.org/logbook/showthread.php?tid=548, MirrorReflectivity_Lustermann_FACT.txt).
# The three values for the reflectivity per wavelength in the original document were averaged.
# For a wavelength of 900 and 950 two values for the reflectivity were estimated.
# The values are NOT multiplied by 1.035 (or even 1.0375, as Julia Thaele supposed in the logbook thread).
# about 4 of 5 values are commented out, to accelerate the spline calculation.
