Hi Geraint,
I think the skim10 wagon used in the unbending data does not select events using the FT-based pid but the regular, forward-detector based pid, which is incorrect. I would recommend not to use it.

Specifically, I am attaching Delta Beta and beta vs momentum plots for protons, and pions, using three data sets as indicated in the slides. Was this issue known?
