  The BAM measures the arrivaltime of** FLASH 1 and FLASH2** in the same data set (thus also sorted in at /FL1/ !). 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) ...

  === 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:
