... Read in data: Fill (x, y, count) data records: Binned mode: x,y: image pixel coordinates count: number of events in pixel Single photon mode: x,y: event coordinates count:=1 Feed data records, background maps, and exposure maps into Maximum Likelihood PSF fitting algorithm: Use Marquarth-algorithm to minimize likelihood function of multi-source PSF fit. Remove sources from fit which do not significantly improve goodness of fit (required improvement in likelihood specified by parameter). ...

... This paper describes the main algorithms used by the Einstein Level One processing to create the exposure masks and the background maps for Einstein IPC images, and how these algorithms were recreated in the IRAF environment. Our goal was to recreate the algorithms used by the Level One Processing to create exposure masks and background maps for Einstein Image Proportional Counter (IPC) data (cf. sections 2.5 and 2.7 of Harnden et al. ...
