Update of Image Deconvolution Software (including SAS package psfgen) Tao Song Dept. Physics & Astronomy University of Leicester

psfgen SAS package (Ver. 0.4) ➲ A handy tool that obtains particular PSFs of the XMM instruments. ➲ Accept vary coordinate systems, i.e. DETXY, XY, RAWXY, TELCOOR. ➲ Accept xmm/evselect generated image as input.

➲ More deconvolution methods. ➲ Allow multiple energy channel deconvolution. (psfgen multiple energy PSFs feature) ➲ Automatically look for proper PSFs for the input data. (psfgen image input feature) ➲ Supply both GUI and function invoke interface. The former is suitable for monitoring changes in deconvolution. The latter is suitable for batch dataprocessing. (psfgen non-interaction feature) ➲ Supply both GUI and function invoke interface. The former is suitable for monitoring changes in deconvolution. The latter is suitable for batch data processing. (psfgen non-interaction feature) ➲ Colour coding for multiple energy channel images. Plan for the new img_decon
