With improved beam spot and position, vz on both spectrometer improved a lot. * On left arm we see 3 foils at around their old locations. * On RHRS run 1807 (only 10% event have track), we also see 3 foils, however they are more twisted with tg_ph. It's even more twisted than LHRS when the initial database used on LHRS. The right bottom of each plot show vz:tg_ph correlation.
