While trying to improve the mediocre performance of my corrector design I
started wondering about my interpretation of some of the formulas in
R&V Telescope Optics.
On page 301 and 302 I have been trying to decide if there are
inconsistencies in the typsetting.
Formula 21.11.2 uses a multiply point sign between hp and the sqrt sign
with no root number in the sign (normal from what I remember from college).
Yet 21.11.4 has a 2 beside the sqrt sign with no multiply point. Are they
saying multiply the sqrt by 2 or are they just emphasizing that it is root
2?
Same thing with 21.11.6 on pg 302, is it r times the sqrt or is it the r root of...?
the results of A B and C seem to be out by  a few orders of magnitude when
I use Oslo to design the schmidt camera. Also, do A B and C relate directly
to the 4th, 6th, and 8th order deformations?
