Introduction

This package contains tools to validate the tracking in the inner detector. This includes tools to fill validation ntuples e.g. with measurement data and a tool for the calculation of SCT residuals and pulls.

Class Overview

The InDetTrackValidation package contains the following classes:

InDet::SCT_ClusterValidationNtupleWriter : Algorithm to write SCT cluster (PRD) data to ntuple

Ntuple variables of the InDet::SCT_ClusterValidationNtupleWriter

SCT_RunNumber	run number	int
SCT_EventNumber	event number for current PRD vector	int
SCT_LumiBlock	event lumi block information	int
SCT_TimeStamp	event time stamp	int
SCT_BunchCrossing	event bunch crossing ID	int
SCT_nRIOs	number of RIOs, i.e. SCT clusters, in the event. This variable set the size of the vectors with cluster information.	int
SCT_DriftRadius	local x coordinate of strip	std::vector<float>	mm
SCT_SurfaceX	global x coordinate of SCT wafer center	std::vector<float>	mm
SCT_SurfaceY	global x coordinate of SCT wafer center	std::vector<float>	mm
SCT_SurfaceZ	global x coordinate of SCT wafer center	std::vector<float>	mm
SCT_BarrelEndcap	from IdHelper: pos/neg barrel (+/-1) and pos/neg endcap (+/-2)	std::vector<int>	1:bar, 2:ec
SCT_LayerDisk	from IdHelper: layer/disk index	std::vector<int>
SCT_EtaModule	from IdHelper: module index in eta	std::vector<int>
SCT_PhiModule	from IdHelper: module index in phi	std::vector<int>
SCT_DeltaPhi	please provide description!	std::vector<float>
SCT_HitErr	please provide description!	std::vector<float>
RDO_SCT_RDO_Group_Size	RDO group size	std::vector<int>
RDO_SCT_Layer	index of the SCT-layer in which the SCT wafer is positioned	std::vector<int>
RDO_SCT_Eta	eta of the SCT wafer	std::vector<int>
RDO_SCT_Phi	phi of the SCT wafer	std::vector<int>
RDO_SCT_Side	side of the SCT wafer (0 or 1) within the SCT module	std::vector<int>
RDO_SCT_Barrelec	barrel/endcap index (barrel: 0, endcap: +/-2)	std::vector<int>
RDO_SCT_FirstStrip	index (could be from 0 to 767) of the fired strip within the SCT wafer	std::vector<int>
RDO_SCT_NumHitsInWafer	number of hits in the SCT wafer	std::vector<int>
RDO_SCT_WaferHash	index (could be from 0 to 8175) of the fired SCT wafer	std::vector<int>
RDO_SCT_TotalNumBSErrs	total number of BS errors.	int
RDO_SCT_BCIDErrs	bunch crossing(BC) ID error - the ROD sets a bit in the link header if the bunch crossing ID for the event it gets ba ck from the link doesn't match its own bunch crossing ID	std::vector<int>
RDO_SCT_LVL1Errs	same as BCID error, but with the LVL1ID	std::vector<int>
RDO_SCT_TimeOutErrs	the ROD sent a trigger to the module but got no data back down the link (perhaps the module is dead)	std::vector<int>
RDO_SCT_PreambleErrs	the ROD found something strange in the header from the link, and set a bit to flag it	std::vector<int>
RDO_SCT_FormatterErrs	the ROD found something strange in the header from the link, and set a bit to flag it	std::vector<int>
RDO_SCT_TrailerErrs	the ROD found something strange in the link trailer and sets a bit there to flag it	std::vector<int>
RDO_SCT_HeaderTrailerLimitErrs	at high trigger rates and/or big events, where the module can't send events fast enough, so just sends headers and trailers, with no hits inbetween	std::vector<int>
RDO_SCT_ABCDErrs	one of the ABCD chips on the module flagged an error - these errors take the place of a hit, rather than being in the header or trailer	std::vector<int>
RDO_SCT_RawErrs	the ROD expected a hit, but the word doesn't match the expected format (e.g. due to opto noise?); this type of error also takes the place of a hit	std::vector<int>
RDO_SCT_BSParseErrs	the ByteStream decoder found something strange - either a strip out of range or something not in the cabling map, or data words that don't match up with any expected pattern	std::vector<int>
