[Comm2011] CCD93

[Konrad Kuijken]

I took a quick look at the negative crosstalk that is now evident in ccd93 since the problems began. Bizarly it does not seem to come from CCD 94, 95 or 96! As an example I looked at 
OMEGA.2011-09-12T02:36:26.148.fits.fz, which is a 5-sec r band exposure on sky. Lots of negative stars in ccd93, but none correspond to the positions of objects on 94,95,96.
I have not had a chance to look if it corresponds to another ccd, or whether the pattern is shifted somehow.
