Description

From Fran├žois:

I have looked at the phase advance for run 8070 (ECE up and down, flip mode) and in run 08155 (ECE up and down + FC, solenoid mode) and I find the expected gyration in both of them. I attached the plots for the up and downstream phase advance, purely global spacepoints.

There seems to be an issue with the sign reported by the tracker reconstruction, however, as it reports -1 upstream and +1 downstream in flip mode (instead of +1, -1, given the wrong field downstream) and the same in solenoid mode (instead of +1, +1, given the right field up and down).
