++== General information about HDF5 ==
  HDF5 is a data format maintained by the HDF group. For detailed general information see [[here>>url:https://portal.hdfgroup.org/display/support||shape="rect"]]
--The easiest way to look at the HDF5 files from your beamtime is to use the **Jupyter notebook** interface to Maxwell:  [[https:~~/~~/max-jhub.desy.de/>>https://max-jhub.desy.de/]]
--
-- The file content can be browsed by double clicking on the file.
--
--Typically the Jupyter notebook starts at your home directory and you have to create a (soft) link to your beamtime folder: open a terminal window (File->New-> Terminal) and create the link via  :
--
--{{code language="none"}}> ln -sn beamtime path linkname
--e.g.
--> ln -sn /asap3/flash/gpfs/fl23/2025/data/11024321/ ~/beamtime_11024321 {{/code}}
--Then a “beamtime_11024321” folder should appear in your home directory.

++* 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 ...
++* 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)
++* There has been also a renaming  (and relocation) of the BAMs.

  If Opis is running typically on the the averaged data is saved. For several experiments it may make sense to save the information for each single bunch. This is up to now done by saving the complete ADC trace of the TOF setup. This is a huge amount of data and needs processing. This has to be performed after the beamtime in close contact to [[Markus Braune>>mailto:markus.braune@desy.de||shape="rect"]] ( responsible for [[OPIS>>url:http://photon-science.desy.de/facilities/flash/photon_diagnostics/opis_spectrometer/index_eng.html||shape="rect"]])
