Detailed Description

Calculate the common mode by taking mean of pixel values.

This functor calculates the mean value of the pixels. To create the list of pixels it will check whether the pixel might contain an event such as an photon. If so it will not be included in the mean. There must be a minimum number of pixels without an event before the common mode is calculated.

To calculate the mean a simple accumulating average is done.

User definable Parameters:

PixelDetectors/%name%/HLLProcessing/SimpleMeanCommonMode/{MinNbrPixels}
The minimal number of Pixels that should be found in the range before the common mode value will be calculated. Default is 8
