Some info

This pass called a "tweakpass6" is actually not a reconstruction pass.

Instead in this pass reconstructed slcio files from pass6 taken as an input

to hps-java, which using already reconstructed tracks, applies global alignment

tweaks to track parameters.

This is supposed to be equivalent of reconstructing a track with a "tweaked" detector.

In addition to above changes

  • In this pass track states in 1st and 2nd layer of SVT is added
  • Event time is calculated using the RF time, which is determined through the highest energy cluster in the event. The cluster indices of that crystal is preserved 
  • This pass has a new format root files "from ntuple maker", that were previously used, but wasn't considered in the pass, it includes Moller, fee, and tri skims
  • v0 skim is dropped, since it was determined to be "too tight"
