PixelTempRewgt2D()

int SiPixelChargeReweightingAlgorithm::PixelTempRewgt2D ( int  id_in, int  id_rewgt, array_2d &  cluster  )

inlineprivate

Reweight CMSSW clusters to look like clusters corresponding to Pixelav Templates.

Parameters

id_in	- (input) identifier of the template corresponding to the input events
id_rewgt	- (input) identifier of the template corresponding to the output events
cluster	- (input/output) boost multi_array container of 7x21 array of pixel signals, origin of local coords (0,0) at center of pixel cluster[3][10]. returns 0 if everything is OK, 1 if angles are outside template coverage (cluster is probably still usable, > 1 if something is wrong (no reweight done).
