adapt_2000 adaptively smooths background subtracted and exposure corrected mosaicked images. For each unmasked pixel, the program will average neighboring pixels within a circle of increasing radius until a selected number of weighted counts from the count image is reached. The original pixel is then given the weighted average surface brightness for the pixels within the circle. Binning by 2 or 4 and of different bands can also be selected.
Warning and requirements: adapt_2000 is part of the package esas, integrated into SAS, but is limited to work within the esas data reduction scheme. This is specially true wrt structure and names of the input files. In particular, adapt_2000 assumes that all tasks to create images from the individual observations have been run as well as the the task merge_comp_xmm which mosaics the different components.
