RHESSI Albedo Imaging Test

The RHESSI Albedo Imaging test continued.

The following steps were attempted with Pixon:

The table below shows the detector combinations

The plot shows the flux profiles of images made with Pixon from a map with two offset Gaussian sources, one with a standard deviation of two arcsecs and one with a standard deviation of 10 arcsec. The seperation of the two sources is 4 arcsecs. The plots were made from images using detectors 1 to 9, detectors 1 to 4, and detectors 4 to 9.
