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
