LVC Skymap and CGBM FOV
HXM Boresight (R.A., Dec.) = (33.1 deg, 47.0 deg)
SGM Boresight (R.A., Dec.) = (25.0 deg, 38.9 deg)
Summed LIGO probabilities inside the HXM FoV : 29.4% (2.94e-01)
Summed LIGO probabilities inside the SGM FoV : 70.4% (7.04e-01)
Summed LIGO probabilities inside the earth occulted region : 12.6% (1.26e-01)
CGBM Field of View. Gray region shows earth-occulted region of sky. Blue
curve marks edge of SGM FOV (zenith angle + 90 deg). Red curve marks HXM
zenith + 60 deg. Green shows LVC high probability region. When earth occulted
region is below (above) red and blue CGBM FOV limits, allowed region is above
(below) red and blue curves. Blocking by ISS structures was not considered.
