Summary:

In STAR's most recent productions of 14.6 GeV and 7.7 GeV collisions, both taken in 2019, the EPD is not calibrated.

I would like to know the status of all datasets of the calibrations.  Is there a table of which runs the EPD has been calibrated and which have not?

STAR took a short run of 7.7 GeV Au+Au data in 2019, and it was produced with production P19ic.  Also there was a production of 14.5 GeV with the same library.  : www.star.bnl.gov/public/comp/prod/DataSummary.html

When I look at the EPD nMIP spectra, it is clear that they are not properly calibrated, for either of these datasets.  As you know, our calibration pretty much just means making the single-MIP peak show up at one. 

I am surprised that any production was done without calibration.

East and West rings are summed, here:


Figure 1 - dN/dnMIP for 14.6 GeV production done with P19ic.



Figure 2 - dN/dnMIP for 7.7 GeV production done with P19ic.

For Skipper: a suggested way to keep track of calibration status.
