This is a filter module which implements skipping for the events which have too low signal in CsPad. filtering algorithm can be controlled trough the module parameter and/or parameters in calibration file. The name of the calibration file is "filter" and it will be searched in the standard calibration directories of the experiment.

Module configuration parameters:

• inputKey (default is empty) – string key used to locate uncalibrated data objects in event
• source (default is "DetInfo(:Cspad)") – data source address
• skipIfNoData (default is "yes") – when set to "yes" if the module does not find CsPad data in an event then it skips event
• mode (default is -1) – filtering mode, see below
• parameters (default is all 0) – list of parameters for filtering algorithm, up to 16 floating numbers

Parameter mode defines where the filter get its parameters and how it works. If set to -1 (default) then it reads parameters and actual mode value from a calibration text file which should contain one integer number for mode and up to 16 floating point parameters. If parameter is set to 0 or if the value read from file is 0 then no filtering is done, all events are passed through. If mode is set to 1 (from parameter or file) then filter calculates the number of pixels above certain threshold. Filter expects two values in parameter array: threshold for pixel value and minimum number of pixels above threshold. If second parameter is negative then it's assumed to be a percentage of the full number of pixels.

Filter works on individual image arrays (quadrants). Module checks for CsPad::DataV1, CsPad::DataV2, and CsPad::MiniElementV1 objects in that order. If any object is found then module runs filter on images in that object. If any one image passes the filter then module returns and event is passed to downstream modules, otherwise framework skips this event.

Package CSPadPixCoords

Package CSPadPixCoords calculates the 2x1 section, quad, and CSPad pixel coordinates and produces the image.
