Detailed Description

Event Setup object which holds DB information for all pixels.

Event Setup object which holds DB information for all pixels. DB info for a single pixel is held in SiPixelDbItem, which contains pedestal, noise, gain and status bits packed into an 32-bit wide unsigned int. The bit allocation is the following: bits [31:24] - status (0 if good, bits TBD set if not good) bits [23:16] - gain (upper 4 bits integer part, 4 bits fractional part) bits [15:8] - pedestal (upper 6 bits integer part, 2 bits fractional part) bits [7:0] - noise (upper 6 bits integer part, 2 bits fractional part)

Event Setup object which holds DB information for all pixels. DB info for a single pixel is held in SiPixelDbItem, which is a bit-packed 32-bit word.
