Using the P24iy_calib2 calibration production and repeating what I did for h-/h+ in Run 19 19.6 GeV with new TPC alignment ...

To begin, here are my usual set of fits and fit parameters for the double ratios of h^-/h⁺:



And the subsequent fit parameters:

Next is a direct comparison with the results for the Run 19 AuAu 19.6 GeV collision data. Here I first show the west sectors, 1-12, with global tracks on the top two rows, and primary tracks on the lower two. The 19.6 GeV data is the darker colors red & blue, and the 14.5 GeV data is the lighter colors orange and cyan.



Similarly for the east sectors 13-24:



Retaining the same colors as above, here are the fit parameter comparisons for globals (top) and primaries (bottom), showing how the sector-to-sector variations are to first order unchanged between the two datasets, pointing to a static source of the variations (a static field distortion, or more likely, sector-wise alignments):
