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

  2. 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.

  3. psfgen vs. calview psfgencalview

  4. 200eV psf.fits image.fits psfgen 5000eV 200 x 200 200 x 200 12000eV 200 x 200 Example of psfgen – Image input Command: psfgen imageset=image.fits level=ELLBETA energy=‘200 5000 12000' output=psf.fits

  5. Example of psfgen – TELCOOR input Command: psfgen instrument=EMOS2 level=ELLBETA energy='300 3000 8000 13000' weight='1 1 0.5 0.5' theta=400 phi=45 output=psf.fits 3000 eV Combined 300 eV 8000 eV 13000 eV

  6. 3000 eV Combined 300 eV 8000 eV 13000 eV

  7. Length (Theta) DETXY TELCOOR Angle (Phi) Test of psfgen – position accuracy

  8. Test of psfgen – coordinates conversion

  9. New Version img_decon fun1 fun2 fun3 GUI Plan for the new img_decon Current Version img_decon Common Blocks Var1 var2 . . . fun1 fun2 fun3 GUI

  10. Plan for the new img_decon • 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) • Colour coding for multiple energy channel images.

  11. Thank you!
