The flare of 2002 Mar 17 appears to be relatively compact, so point source models were fitted to several of the detector profiles.
In simplified form, the equation of fit is simply:
where
Point-source fit to Detector 8, 17 Mar
Point-source fit to Detector 7, 17 Mar
Point-source fit to Detector 6, 17 Mar
Point-source fit to Detector 5, 17 Mar
Point-source fit to Detector 4, 17 Mar
