# Average quantum efficiency of 382 PMTs of Hamamatsu type R12992-100-05 in 420 measurements.
# Data from Oleg Kalekin, University Erlangen, March 2018.
# Based on measurements in a circle of 10 mm diameter in the center of the cathode,
# limited by the size of the reference photodiode.
# (Note that some tubes have a dip in sensitivity in the center while
# most are relatively flat in response. Not sure if this is representative (K.B.).)
#
# Col. 1: wavelength [nm]
# Col. 2: average QE [0...1]
# Col. 3: r.m.s. of individual QE values (not used by sim_telarray)
# Col. 4: r.m.s. of QE values after normalizing each PMT to the same
#         mean value in the 350-450 nm range (not used by sim_telarray)
