422 +* The data format of the BAM has been completely altered in the 2022 shutdown
423 +* 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 ...
424 +* THIS is now different. there are new parameters for pulses that go to FL1 and to FL2 (in detail: first time slot of the accelerator and second)
425 +* There has been also a renaming  (and relocation) of the BAMs.
