Detailed Description

A template management class. SiPixelTemplate contains thePixelTemp (a std::vector of SiPixelTemplateStore, each of which is a collection of many SiPixelTemplateEntries). Each SiPixelTemplateStore corresponds to a given detector condition, and is valid for a range of runs. We allow more than one Store since the may change over time.

This class reads templates from files via pushfile() method.

The main functionality of SiPixelTemplate is interpolate(), which produces a template on the fly, given a specific track's alpha and beta. The results are kept in data members and accessed via inline getters.

The resulting template is then used by PixelTempReco2D() (a global function) which get the reference for SiPixelTemplate & templ and uses the current template to reconstruct the SiPixelRecHit.

bool SiPixelTemplate::simpletemplate2D	(	float	xhit,
		float	yhit,
		std::vector< bool > &	ydouble,
		std::vector< bool > &	xdouble,
		float	template2d[BXM2][BYM2]
	)

Make simple 2-D templates from track angles set in interpolate and hit position.

Parameters

xhit	- (input) x-position of hit relative to the lower left corner of pixel[1][1] (to allow for the "padding" of the two-d clusters in the splitter)
yhit	- (input) y-position of hit relative to the lower left corner of pixel[1][1]
ydouble	- (input) STL vector of 21 element array to flag a double-pixel starting at cluster[1][1]
xdouble	- (input) STL vector of 11 element array to flag a double-pixel starting at cluster[1][1]
template2d	- (output) 2d template of size matched to the cluster. Input must be zeroed since charge is added only.
