Imaging the Albedo with Pixon
The following show Pixon images for simulated data of a point source with albedo. Each image shows the contours for the Pixon reconstruction overlaid on the a map of the original data. Below each image are the profiles for the data and the fit showing the C statistic for each detector. For each image the following parameters were used: Time: 2-September-2002 00:07:36 - 00:08:20 Detectors: All Detectors Image Size: 64 X 64 Pixel Size: .5 X .5
Above each image is the total counts in the final image. Below each image is the source size data as calculated using the 3 sigma source size program written by Rick Pernak.

The following plot shows the profile for each detector compared with the fitted profile along with the C statistic for each detector.
The total counts in the final image below is: ~10e5 counts
The 3 sigma parameters for the reconstructed image assuming an elliptical source are:
Source Flux: 310.592 Source X: 301.157 Source Y: -0.344853 Source FWHM: 3.94633 Eccentricity: 0.0599250 Source Angle: 107.000
The following plot shows the profile for each detector compared with the fitted profile along with the C statistic for each detector.
The total counts in the final image below is: ~10e6
The 3 sigma parameters for the reconstructed image assuming an elliptical source are:
Source Flux: 1473.15 Source X: 301.232 Source Y: -0.429101 Source FWHM: 4.42663 Eccentricity: 0.260343 Source Angle: 167.000
The following plot shows the profile for each detector compared with the fitted profile along with the C statistic for each detector.
