dE/dx calibration for 17p3GeV and dAu200 2021 have been put in MySQL  on 2023-08-04.
The results of tests using MySQL constants with SL23b can be found at https://www.star.bnl.gov/~fisyak/star/PiD/RunXXI/17p3GeV_dAu200_2021_RunXXI306/

The resolution 

and shift 

look o.k. But Gain variation versus sector and pad row

looks suspicious. I need 3 or more iteration to finalize.
