829 -* before 2022 BAMs were always saving the arrival time information for each 1µs bucked regardless if there were electrons in the accelerator or not. IN addition the arrival times for  FL1 and FL2 were saved in the same parameter ...
830 -* THIS is now different. There are new parameters saving only the arrival times for pulses that go to FL1 and to FL2 (in detail: first time slot of the accelerator and second)
831 -* There has been also a renaming  (and relocation) of the BAMs.

1277 1277  desc: Besides the well calibrated averaged beam position information there is also the option to measure the beam position on a single bunch level. HOWEVER this methide needs a perfectly adjusted signal level (talk to your local contact !!) and also then the signal to noise is rather small and one needs some averaging ... BUT with this option one can determine if there was a spatial slope on a burst (say forst bunches were lower than the last ones or so ...)
