Hi Andrei,

I presume you’re using the wavefront map analysis feature? That shows the wavefront error across the pupil, so it is in pupil coordinates, so that +/-1 represents the EXPDiameter of the pupil. The plot shows the wavefront in pupil coordinates and EXPD and EXPP are reported elsewhere. In fact, the EXPD is reported in the rubric of the wavefront map, I think.

If ‘Use Exit Pupil Shape’ is selected the map is distorted in x and y coordinates based on the x and y f/#s, which are also reported elsewhere. 

If you put a dummy surface at the exit pupil location, the footprint on that surface and the wavefront map outline should be in broad agreement. Note that the footprint is on the surface, whereas the wavefront map is based on what you’d see at the image point for the specified field/wavelength.
