The dosing for off-aimpoint observations was investigated using MARX simulations at increasing offsets up to 22.5'. The Table's "Peak Dosing" presents the peak pixel dosing achieved versus offset angle compared to an on-aimpoint observation.
The rightmost column gives the inverse of this, which can equivalently be understood as the brightness increase required for a source at an offset to produce the same dosing as one at the aimpoint.
For instance, a 7 Crab source offset by 7.5' would produce an equivalent peak-pixel dosing as an on-aimpoint 1 Crab source. Or, a 1 Crab source offset by 15 arcmin, would produce as much dosing as a 70 mCrab source down the boresight.
