--{{info title="BAM hints"}}
--* The BAM 4DBC3 measures the arrivaltime of** FLASH 1 and FLASH2** in the same data set (thus also sorted in at /FL1/ !).
--* The BAM 8FL2XTDS measures only for FLASH2 BUT has the same data structure as the other BAMS ... thus there are also (random) values in in the  FLASH1 time slot
--** Structure: The first values are for FLASH1 bunches. After a gap of about 70 micros ( 70 colums)  with  as entry for the switching between FLASH 1 and 2 the values for the electrons used in FLASH2 start.  The start time of FLASH2 is also recorded in the DAQ. FLASH1 start time is for historic reasons 700. thus if e.g. the start time of FLASH2 ( property name see below) is 1200 it means that FLASH starts at column 500 (1200-700) ... .In case of doubt ask your local contact

--desc: The max 600 µs acceleration time of FLASH is devided between FLASH1 and FLASH2. This 600 µs window starts with FLASH1 (up to now)  at a time"label" of 700 µs (for historic reasons). Thus the first bunch of FLASH 1 comes at "700" and the last possibel bunch comes at 1300 (700+600). After FLASH1 train is over ther is a about 70µs switching time with no bunches. Then comes the first FLASH2 bunch.  Thus if e.g. the start time of FLASH2 is 1200 it means that FLASH2 starts at column 500 (1200-700)  in the HDF5 files. (However for yet unknown reasons this may change by 2-3 colums ...)

  === HDF5 structure revisions ===
  Starting with Beamblock 4, August 2018, the hierarchy of the HDF group names have been adapted to reflect the new situation at FLASH. FLASH2 is operating for users quite some time now. Therefore, both accelerators appear equally in their respective HDF groups, namely "/FL1" and "/FL2". The root group of proper, by run organised HDF files have an attribute called "version". This version attribute has changed from "0.2.x" to "0.3.x". The changes in detail:
