fexpoadapt -- Adaptively smooth an image and an exposure map together.
fexpoadapt image expomap smooth mincounts [minexpo]
This is a boxcar smoothing program that works on an image and the exposure map associated with it simultaneously. A pixel with exposure less than 'minexpo' (typically 0) is set to 0; otherwise, this accumulates values from surrounding pixels until it has at least 'mincounts' counts. The total is then divided by the total of exposures accumulated from the same pixels.
1. Smooth gis.img, with associated exposure map gis.expo, to contain a minimum of 100 counts per cell; output the result into gis_smooth.img
ex> fexpoadapt gis.img gis.expo gis_smooth.img 100
This tool has not been tested extensively except on ASCA images.
