Effects of offset in distortion maps

At today's TPC meeting, Yuri asked what would be the effect on the distortion maps (particularly SpaceCharge & GridLeak as the largest distortions) if the z-axis of the TPC was offset (e.g.

Run 12 pp200 production peek at dE/dx in the MuDst

These are plots of primary track dE/dx nSigma quantities stored in the MuDsts with no cuts other than nSigmaPion > -5e5 (there is some class of tracks with very large negative nSigmaPion).

Hit occupancy with luminosity in Run 12 pp510

Mean number of TPC hits per padrow per event averaged over sectors vs. luminosity (depth in the histograms).

Iterative DoDistortions in StMagUtilities

StMagUtilities corrections for distortions were implemented with the expectation that the displacements due to distortions do not vary significantly over distances comparable to those displacements.

A glance at TPC gas gains

I had some confusion about the gas gain in the TPC, so I've decided to document what I've seen...

One can write the gas gain as an exponential:
