Testing Image Reconstruction Algorithms

I've started running tests of the Clean image algorithm using the simulated data agreed upon at the RHESSI Workshop. I've started with the first image, a line source as the test case. In the case of the line source the clean image, shown below as contours on the original data map, was obtained.

The original line source with with the contours of the Clean Image overlaid

This Clean image was obtained with a clean_beam_width_factor = 2.0.

The following profiles were obtained with this image:

The profiles of the fits for each detector compared to the original simulated data

As is clear from the above profiles, either the calibrations of the detectors is incorrect or the Clean Image and profiles are not correlated.

Using Richards routine to obtain the total C statistic yields a value of:

Total C Statistic = 6.37
