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 xytemp(), 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.

Interpolate stored 2-D information for input angles and hit position to make a 2-D template

Parameters:
id- (input) the id of the template
cotalpha- (input) the cotangent of the alpha track angle (see CMS IN 2004/014)
cotbeta- (input) the cotangent of the beta track angle (see CMS IN 2004/014)
locBz- (input) the sign of this quantity is used to determine whether to flip cot(beta)<0 quantities from cot(beta)>0 (FPix only) for FPix IP-related tracks, locBz < 0 for cot(beta) > 0 and locBz > 0 for cot(beta) < 0
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.

Interpolate stored 2-D information for input angles and hit position to make a 2-D template

Parameters:
id- (input) the id of the template
cotalpha- (input) the cotangent of the alpha track angle (see CMS IN 2004/014)
cotbeta- (input) the cotangent of the beta track angle (see CMS IN 2004/014)
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.
