Pixon Albedo Imaging
Using Eduard Kontar's simulated eventlist files, Pixon Images were created for a compact circular gaussian source with an albedo contribution near disk center, and near the limb. The following parameters were used for each image:
- Time: 2-Sep-2002 00:07:36 - 00:08:16
- Energy 24keV - 51keV
- Detectors 1 to 4
- Image Size: 64 by 64 pixels
- Pixel Size: .5 arcsec by .5 arcsec
The following plots are extensions of the plots from the previous report.
The plot below shows the gaussian model of the compact source (orange),the original data map with the minimum and maximum value at each radial distance (Black), the Pixon image with the minimum and maximum value at each radial distance (Purple), and the clean image with the minimum and maximum value at each radial distance (Cyan)for a source near disk center.
