Rough summary: AuAu27 calibration quality is near that of AuAu19.6 when it was produced last month. IMPORTANT: This is "first look" quality, and should not be construed as presentation/publication quality!

Slightly more detail of differences between current AuAu27 calib and AuAu19.6 calib:

• TPC (more details available from Maxim)
  • Anode voltages: list of good/questionable runs known; DB tables not yet updated for questionable runs which can be repaired
  • T0/Twist: not yet examined for FF (RFF values in place)
  • SpaceCharge+GridLeak: preliminary values can be ready by end-of-the-week (no significant effect seen in AuAu19.6, while it was seen in AuAu27), would provide a very small (~1mm spatially) improvement in track pointing and pT resolution over FastOffline results
• FTPC
  • Rotation alignment: not yet examined
• TOF
  • AuAu19.6 calibs about as good for AuAu27 in "start-less" mode (i.e. not using VPD)
• BEMC & EEMC
  • Status & pedestal tables not in place for either AuAu19.6 nor AuAu27
  • Gain: not needed for production, otherwise old calibs suffice
• PMD
  • Not yet examined for AuAu27 (was done for AuAu19.6)

Other than TPC SpaceCharge+GridLeak (and establishing a list of good/questionable runs), essentially the same as FastOffline.

Development of a calibration deliverables schedule is called for, to be matched with PWG priorities and needs for calibration quality.
