The aberration coefficients for the concave grating mountings are derived
assuming the pupil is at the grating. Given the hmited sizes of concave gratings,
this is the only practical way of using the grating. A plane grating has no preferred
axis and the aberration coefficients are independent of the pupil location.
For each of the grating mountings, we now determine the curvature of the
image surface on which the tangential astigmatic images ar ...
