Detailed Description

Pixel cluster – collection of neighboring pixels above threshold.

Pixel cluster – collection of pixels with ADC counts.

Class to contain and store all the topological information of pixel clusters: charge, global size, size and the barycenter in x and y local directions. It builds a vector of SiPixel (which is an inner class) and a container of channels.

March 2007: Edge methods moved to RectangularPixelTopology class (V.Chiochia) Feb 2008: Modify the Pixel class from float to shorts May 2008: Offset based packing (D.Fehling / A. Rizzi) Sep 2012: added Max back, removed detId (V.I.) sizeX and sizeY now clipped at 127 July 2017 make it compatible with PhaseII, remove errs....
