Introduction

The following classes are defined

• TrigInDetTrackFitPar : represents a set of LVL2 track parameters with associated covariance
• TrigInDetTrack : a LVL2 track containing TrigInDetTrackFitPar(s) and input data - Pixel and SCT spacepoints and TRT drift circles
• TrigSiSpacePoint : a LVL2 spacepoint in Pixel or SCT
• TrigVertex : a LVL2 vertex class containing vertex coordinates, covariance matrix, and some auxilliary information about vertex
• TrigHisto : A base class for TrigHisto1D and TrigHisto2D, contains common code. Not stored directly. TP converters do not persistify this class.
• TrigHisto1D : A class to store a 1D histogram for a given event and provide cut functionality. This class is used by TrigTrtHitCounts.
• TrigHisto2D : A class to store a 1D histogram for a given event and provide cut and profile functionality. This class is used by TrigSpacePointCounts and TrigTrackCounts.
• TrigSpacePointCounts : Contains 3 histograms (TrigHisto2D of Pixel cluster time over threshold vs size, for endcap C, barrel and endcap A. It also contains the total number of SCT space points for endcap C, barrel and endcap A.
• TrigTrtHitCounts : Contains 3 histograms (TrigHisto1D) of TRT time over threshold for endcap C, barrel and endcap A.
• TrigTrackCounts : Contains 2 histograms (TrigHisto2D) of track z0 vs pt and eta vs phi respectively

This package also contains selection.xml - a file for lcgdict generation
