Calibration Access and Data Handbook

Generation from Ground Calibration Data

The radial distributions were generated from the CSL pinhole images. The accuracy of the derived distributions is hampered by the uneven illumination of the detector and the change in PSF width originating in the CSL collimator.
The analysis was performed in the following steps.

• localizing sources with daofind (noao.digiphot.daophot)
• generate radial profile with pradprof (cl.plot)
• normalize radial profiles
• average radial profile in central detector area
