TrackerAlignment _forRun2015D_v0

!!! WARNING: WRONG CONDITIONS - do not use!!!

This tag was supposed to contain the alignment constants derived from Run2015B data (internal reference mp1834), but it actually contains constants derived from Run2015C data (internal reference mp1835). These are not usable on any other data than that of Run2015C because of a wrong pixel voltage bias during that era, which leads LA-corrections that are incompatible otherwise.

TrackerAlignment _v1_hltvalidation (CRUZET+CRAFT alignment)

Tag at CondDB.

Tracker alignment and surface deformations derived from CRUZET and CRAFT data. Full module level alignment.

MP+HIP alignment, internal reference sm1107 xiaomeng/SetAPE/CMSSW_7_4_0_pre6/src/Alignment/HIPAlignmentAlgorithm/sm1107_2/alignments.db

1. MP alignment mp1700 (MPproduction/mp1700/jobData/jobm/alignments_MP.db) with separate IOVs for CRUZET and CRAFT data (due to technical reasons 2nd IOV: CRUZET, 4th IOV: CRAFT, in between dummies (1st and 3rd IOV)), aligning also surface deformations
2. HIP alignment run on output of mp1700 (CRAFT IOV) to optimize module positions (surface deformations kept from mp1700)

The conditions are:

• GT GR_P_V49
• SiPixelTemplateDBObjectRcd: tag SiPixelTemplateDBObject_38T_2015_v1

TrackerAlignment _ppRef2015_hltvalidation

Tag at CondDB.

Tracker alignment derived from the Pseudo-PCL workflow on run 262205.

APE Objects (Data)

TrackerAlignmentExtendedErrors _forRun2015C

Tag at CondDB.

Same as ape_DESRUN2_74_V4_barrel10-disks20

ape_DESRUN2_74_V4_barrel20-disks40

Simple APE: average APE for each subdetector. Determined from IDEAL MC by introducing a random misalignment such that the track-hit residuals observed in data are reproduced. The values are tuned based on the DMR (distribution of the median of the residuals) and DRR (distribution of the RMS of the residuals) plots.

SQLite file at: /afs/cern.ch/cms/CAF/CMSALCA/ALCA_TRACKERALIGN/PayLoads/2015_APEfor25ns_38Tand0T/ape_DESRUN2_74_V4_barrel20-disks40.db

The APE are 20μm in all barrel detectors and 40μm in all disk detectors.

Derived for start-up of collision-data taking. Derived from CRAFT data, with CRAFT-data alignment. Actual performance found shows rather 10/20μm, but this is probably overly optimistic as validated on CRAFT data with CRAFT-data alignment (well-aligned detector for that data, not all modules illuminated), therefore a conservative 20/40μm was chosen.
