# Exchanging pixel positions against those of matching pixels in ../cfg/CTA/checs_pixel_mapping_v2.dat

# As a result, any comments below about the estimated field-of-view

# This version of modular_camera was compiled for the SixtyFourSquarePixelGenerator module pixel generator.
#
# Modular camera with 32 modules of 64 pixels each.
# Each of the 2048 pixels has a size of 0.620 cm (flat-to-flat, square).
# Between pixels is a gap of 0.020 cm. Pixel spacing is 0.640 cm.
# Between modules is an additional gap of 0.200 cm.
# The pixel spacing corresponds to 0.171 deg at f=2.150 m for pixel plus any gap.
# The camera has a nominal diameter of 0.340 m (radius 0.170 m), resulting in a
# nominal field-of-view diameter of 9.04 deg at a focal length of 2.150 m.
# Pixel centers are within a radius of 0.187 m (max. pos. FoV diameter 9.962 deg.).
# All pixel corners are within 0.191 m (max. corner FoV diameter 10.141 deg.).
# Pixels with less than 8 neighbours within 1.217 cm are assumed edge pixels.
# The edge starts at a radius of 0.150 m (contiguous FoV diameter 7.956 deg.).
# Mean radius of camera edge is 0.169 m (mean FoV diameter 9.003 deg.).
# Area covered by pixels+gaps: 0.073 m^2 (equivalent radius: 0.152 m, FoV 8.09 deg.)
#
# Attempting to wrap pixel positions onto a sphere of 1.060 m radius but
# keep in mind that this may not be physically possible because of collisions.
#
# The angular efficiency of funnels is read from file 'funnel_perfect.dat'.
