This is true for the pure PSF which I create, but afterwards I apply ``postprocessing'' where I convolve the image with the fiber size, grating effects, scattering and charge diffusion. All of these effects are symmetric and should not modify the center  of light. Observing the result we see that this is not the case. This is probably because I was not careful about this, as centering was never issue for me until now. </p> PIPE2D-474

Position of center of light gets moved in PSF postprocessing

For perfectly illuminated pupil, without any abberations, the center of light aligns exactly in the center of the array. For 211x211 array, the center of light is at pixel 105. </p> <p>I also added the image showing the difference between the position of the chief ray and the center of light.</p> <p> </p> Relates PIPE2D-450 Development Rank 0|02qpt6:508yl0chzzy0000p93 Sprint 2DDRP-2019 J Story Points 4.0
