14 HDF5 is a data format maintained by the HDF group. For detailed general information see [[here~[~[image:url:http://hasfweb.desy.de/pub/TWiki/TWikiDocGraphics/external-link.gif~|~|width="13" height="12"~]~]>>url:https://portal.hdfgroup.org/display/support||shape="rect"]]

30 == The FLASH HDF5 format ==
31
32 FLASH provides a conversion of its data acquisition (DAQ) to the commonly used [[HDF5>>url:https://www.hdfgroup.org/solutions/hdf5/||shape="rect"]] format. Correlated  data are mapped by a primary index called **train ID**. Every data set has an individual index of train IDs to identify the data even when data are missing or deviate in update rate. If the data set of choice contains gaps,  users have to decide how to treat missing values. DAQ channels are spread across various files with one file name pattern for each DAQ. This means users have to assemble data from different files if necessary.
33
34 The hierarchy is realized using a human readable named HDF tree with each DAQ channel containing the data sets "//value//" and "//index//". Additionally, the HDF group //zraw// contains a tree of the original DAQ channel names.
35
36 Reference implementation, which follows the concept of Python libraries like Pandas, Xarray, or Dask, is given below.

41 === Comparison to FLASH's deprecated HDF formats ===
42
43 Before 2021, FLASH provided two different HDF formats formally known as //near-online// and //offline// HDF files.
44
45 All data sets were aligned by the same global index by filling in missing data. Fast DAQ channels  (pulse synchronous data - update 10 Hz) are filled in by NaN or 0, slow channels (not pulse synchronous data - update e.g. 1 Hz ) are interpolated by the DAQs libraries, by keeping the value constant up to the next change.
46
47 While the near-online HDF files were converted live during the beamtime, the offline HDF files were manually compiled weeks/months later. Near-online HDF files were used by a provided API [[BeamtimeDaqAccess>>url:https://confluence.desy.de/display/FLASHUSER/Near-Online+data+analysis#Near-Onlinedataanalysis-BriefUserGuidetoBeamtimeDAQAccess||shape="rect"]], which also searches for DAQ channels in files. With assembled files "by run", all DAQ channels were existing in the same HDF file. While shorter runs usually fitted into one file, longer runs still had to be aggregated over several files. The creation of the assembled type of files still involves the use of fairly unstable DAQ Mex-functions As the environment required for using the Mex-functions is already deprecated, its continued existence is uncertain.
48
49 The HDF hierarchy is almost identical in all formats. While in the the recent format each DAQ channel contains the data sets "value" and "index", the deprecated format had one data set for each DAQ channel. The deprecated formats supplies no time axis parameters for spectra data types.

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 ...)

903 * The BAM 4DBC3 measures the arrivaltime of** FLASH 1 and FLASH2** in the same data set (thus also sorted in at /FL1/ !).
904 * 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 
905 ** 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

924 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.

1082 === HDF5 structure revisions ===
1083
1084 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:
1085
1086 \\
1087
1088 * All FLASH1 related HDF groups moved to group "/FL1", i.e. a new prefix "/FL1" is added to their HDF path.
1089 * The ambigious term "pulse" has been replaced by "train" to refer to "pulse train". Most notably, the dataset "/Timing/pulse ID" has changed to "/Timing/train ID".
1090 * A number of inconsistent names have been streamlined. The relevant changes are listed in the following table.
