# originally written by rje, based on HXDS aperture measurements table
# dated Nov 13, 1996
#
# Nominal aperture sizes (i.e. diameters of circular apertures
# are in mm (fpc's) or microns (ssd_5), as in aperture logs.
# Aperture areas are uniformly in cm^2.
#
# Mesh corrections of 0.9025 are included in all fpc areas except fpc_5_1.
#
# The fpc_hs_37 is actually the blocking plate on fpc_x2, used in the
# fpc_hs position during the "I"-phase of the flatfield testing.
#
# Areas of fpc_h*_full apertures assume 1/4" radius circular corners
#
# adding ap_area_error from Brad's CAT memo of 11 Sep 97
