OCI l2gen polarization correction verification
Verify that the frame rotation angle (alpha) for OCI polarization correction is implemented, and verify with Fred Patt that the calculation is correct.
I do not see where l1rec->alpha is even updated for OCI, as it is in Hawkeye for example:
l1_hawkeye.c: compute_alpha(l1rec->lon, l1rec->lat, l1_hawkeye.c: mnorm, l1rec->npix, l1rec->alpha);
This is related to #588 (closed)
