TPC tracking accuracy (by Gene):
I sampled processed data from runs 10078077-10089004 and found that the TPC shows much work to be done, but it appears accurate to say things are controlled to the 1-2mm level.

GridLeak measure of gap in residuals between padrows 12 and 14 vs. z shows about a ~1mm variation over all z:

|
Signed DCA of straight up (|eta|<0.05) tracks vs. z shows about ~2mm distortions a Z beyond +/-50cm. For Z restricted to +/-25 cm the distortions are ~0.3mm with sigma of 0.4mm

Signed DCA of all "good" tracks has a mean of ~1mm, sigma of ~3mm:
