Detailed Description

pixel detector common mode background calculation

Available PostProcessors:: "334": pixel detector common mode calc using histograms

See also: Processor for a list of all commonly available cass.ini settings.

User definable Parameters:

Processor/%name%/{Image}
the image of the pixel detector

Processor/%name%/{Width}
when using the histogram option this is the width of the 0 photons peak that the CsPAD typically has. Default is 30

Processor/%name%/{MaxDistance}
How much should the histogram value differ at the most from the unbonded pixel value, before the value of the unbonded pixel is taken. Default is 5

Processor/%name%/{EnableChecks}
Switch that allows to enable checks by outputting the histograms, and the found maxima. Default is false.

void pp334::process	(	const CASSEvent &	evt,
		result_t &	result
	)

virtual

overwrite default behaviour don't do anything

define a few things for the hisogram and asics

create list of histograms

iterate through image

get the pixel value

skip pixel if it is masked

find out in which row of the image we're

find out where we're on the row

find out on which asic of the chip we're

find out which chip we're on

calc which asic we're on

determine the bin in which the pixels values will fall

check if the bin is out of bounds, if so skip it

add the pixel to the histogram

determine the center of mass of the first peak in each histogram

go through unbonded pixels of each asic of image and calculate the mean

check if the maximum of the histogram is close to the mean of the unbonded pixels, if so than the common mode is the value determined by the histogram, otherwise its the mean value of the unbonded pixels

set the pixels of the result to the determined common mode value

iterate through image

get the pixel value of the original image

skip pixel if it is masked

find out in which row of the image we're

find out where we're on the row

find out on which asic of the chip we're

find out which chip we're on

calc which asic we're on

set the common mode value of the pixel

if the checks are enabled add them to the end of the result

set the pos of the output line
