XMM-Newton Calibration Technical Note PN Optical Loading XMM-SOC-CAL-TN-0051 Issue 1.1 M.J.S. Smith April 13, 2004 1 Abstract An investigation into PN optical loading has been performed through analysis of PN o set maps. ... Assuming an o set created solely by optical photons and a gain of 5 eV per ADU, the conversion from residual o set to optical counts per pixel is: 1 ADU  5=3:65 optical photons. ... Fig. 1 shows an example of optical loading cases in a PN residual o set map. ...
