Dear all,
I have reached the conclusion that gain variations across a single chip
seem to correspond to <=0.025mag typically. See top section in
http://wiki.astro-wise.org/projects:omegacam:commissioning:gain for the
argumentation. Please shoot at the argumentation.
This conclusion is relevant on how to treat illumination variations due
to straylight gradients.
Best wishes, Gijs
