M1630 is interesting because (I am using my terminology in the following) for the test at T=+10C ROC1 fails the PH optimization test and by consequence the gain/pedestal test is also failed.
The PH optimization test is failed because the minimum pixel on which the test is based is a 'dead' pixel (according to the PixelAlive test), but unfortunately has hits in the initial PH map. As a result the phscale and phoffset for this ROC are not optimal and this is seen in the gain/pedestal fits.
Please find the plots attached from the T=+10 tests. |
