; Fast Raster calibration constants
; =================================
gusefr = 1
; flag if 1 fast raster data used with average beam pos and angles in
; calculating beam position
; if 0 then only use average beam pos and angles in calculating beam position
; Various fast raster quantities: gUse* are flags
; Raster constants determined from coin run 4556 on Aug 20, 2018
