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.

839 -==== User Data (FLASH2) ====
840 -
841 -The data saved specifically for detectors at an experiment will show up in /Experiment/ there is a large number of options for cameras or monitoring pslow properties (motor positons etc) for user experiments. For details please ask your local contact.
842 -
843 -NOTE: If parameters for an experiment are included on short notice the correct naming in the HDF5 may not be in time and the data will show up in /uncategorized/ with the DOOCS names

845 -The most common and permanently installed device used by experiment are our ADCs:

847 -===== GHz ADCs =====

To read the ADC trace with an online analysis program the {{code language="none"}}CH00.DAQ.TD{{/code}} is used preferablly.

862 -In addition there are also additional parameters saved like:
863 -
864 -* {{code language="none"}}sample frequency{{/code}}: it shows the sample frequency in MHz (number of samples per µs). NOTE: the clock of the ADC is NOT synchronized to the FLASH timing system. Thus the number of samples between bunches in the bunch train may be not integer numbers which will be show up for long bunch trains.
865 -* {{code language="none"}}number of samples{{/code}}: total number of samoles recorded for each 10 Hz trigger
866 -* {{code language="none"}}error (ADC):{{/code}} 0 indicates that there was no error
867 -* {{code language="none"}}/CH0-CH3/offset{{/code}}: To use the full dynamic range of the ADC one can shift the base line . This offset is saved here.

869 -===== MHz ADCs =====

935 935  === HDF5 structure revisions ===
936 936  
937 937  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:
