M1593: B due to Rel.gain width and mean noise of a few ROCs
M1658: B due to threshold and mean noise of ROC15
M1659: B due to threshold and mean noise of a few ROCs
M1660: C due to 172 pixels failed Threshold (trimmed) on ROC7 only at second -20C, the first -20C and +10C trimming threshold is OK for this chip
