Consolidated misregistration/distortion design. Mix and match three distortions to model all effects:
misreg.dm2wfs: DM to WFS distortion
misreg.tel2wfs: Telescope pupil to WFS distortion
misreg.dm2sci; DM to science distortion
telescope pupil misregistration can be simulated by set tel2wfs and dm2sci to opposite values and keep dm2wfs at empty
DM to WFS misregistration can be simulated by set dm2wfs and tel2wfs to same values.
