Summary

Description

English: Abell 2147 galaxy cluster images of each detector showing the region file used for that instrument. The images are smoothed with a Gaussian of 1.5 pixels and are not exposure corrected. The regions inside the solid green circle were extracted for the source spectrum. Regions inside dashed red circles and lines were excluded from the source and background detections.
