This test pass includes

  • New geometry from Alessandra.
  • event time stamp is fixed
  • SVT bias and position flags expected to be fixed on this pass
  • mass and momentum are correct now for detached vertex pairs
  • Doesn't use SVT alignment constants from the conditions system, but instead uses these values from the compact.xml

Checklist of things to verify, before starting the pass1

  •  Look into skims, make sure it is not too tight
    • I have run my calibration analysis for Møllers and V0s over the recon and skim files and get the same events.(Norman) 
  • Check track parameters for detached vertexes
    • Tracks for Unconstrained vertices have been swum to the fitted vertex z position and their parameters updated in the Vertex metadata. TargetConstrained and BeamspotConstrained vertices have not been modified. (Norman) 
  • Check whether we get the target position close to 0
    • Vertices for Unconstrained Møller fits still give +3mm. V0s are slightly negative (~-1mm). FEE are also around -1mm, with a slight discrepancy between top and bottom. (Norman) 
  • Check the event time stamp is correct
