Procedure

The OM CCF component BadPix is read and the entries of bad pixels falling into the specified area are extracted. A value of zero is assigned to defect free pixels in the output map. Bad pixels are marked in the output map by non-zero values. The value assigned to a bad pixel encodes the type of defect. The mapping between CCF description and the integer encoding used in the output badpixel map is as following:

Table 1: Encoding of OM detector defects
type CCF description CAL encoding
turn on channel T 10
hot CCD pixel H 11
edge emission E 12
dead CCD pixel D 13
dead pore P 14
bad CCD pixel B 15
bad for unknown reason U 16
area of reduced sensitivity    
(reduction of sensitivity in steps of 10%) 1-9 1 to 9
