sPHENIX is a new detector at RHIC.

Thanks to everyone who participated in our very useful meeting today.  Here 
are some minutes (also posted on indico):

Analysis Tracking (Anne & Dennis) 
    • No comments

MBD Calibrations/Reconstruction: status & timeline (Stacyann)
    • Question about whether to include the HCal/INTT in the requirement to 
be on the list of runs to be calibrated.  We want to keep the requirements as 
low as possible for the MBD list since all analyses from this data (INTT or 
calorimeter) will require MBD information
    • Question about the timing position as a function of channel (top right 
of slide 3): what are the other peaks to the left of zero?
        • There was no explanation.  Request to have more details about the 
calibration procedure presented at a future meeting
    • Is the code public?  Answer: Not currently.  Timescale of two weeks 
from now to have the final calibrations done.  That code will have to be 
public
        • There will be a presentation in the next PCM.
    • Question about the MBD information from the LL1 LUTs from Dan.  Will 
followup offline.

Calorimeter Calibrations Group (Anthony H. & Blair)
    • There will be a list of places where people are needed soon.  
Encouragement for the many people involved in calorimeter-related PPGs to get 
involved even if they have not been previously.
    • Golden run list of ~100M events with more than 5 SEBs in the EMCal and 
~40M events with 8 SEBs.
    • Questions about the ability to see the eta.  There was a plot showing 
the eta passed around showing an eta peak from the pre-QM dataset.  The peak 
was isolated using timing cuts but it’s not an official set of cuts yet.
    • Question about simulation needs.  Right now it is being done ad-hoc but 
there will have to be a more coordinated effort and more person-power is 
needed.

Centrality (Dan)
    • Joe brought up the issue of not having just a single event vertex 
(mostly not an issue in the Run 23 data but will be in the future).  Dan and 
Joe will discuss offline
    • Question from Takashi about what’s needed from the INTT and Dan and 
Takashi will followup offline
    • Dan showed a parallel effort ongoing to the MBD calibrations discussed 
by Stacyann.  Will of course have one final set of offline analysis but 
checking for consistency between the two efforts is great.
