++* The //average// FEL pulse energy as example for the **slow** **data**. Here the data is not saved with 10 Hz  - thus not for every FEL pulse train.  The data is typically saved with 1 Hz if the values are changing (like the FEL energy) and every about 20 sec if there is no change for longer time ( e.g. motor set values). Thus to use the data together with the "fast" one, one has to interpolate the data as explained in the examples in the repos below show (e.g. {{code language="none"}}df['GMD_T_average'] = df['GMD_T_average'].interpolate(method='linear'){{/code}})

This one was newly installed in 2020.. The property contains only the arrival time of the bunches sent to FL2 (e.g. if there are 30 bunches in FL2 the first 30 values are the arrival time the remaining numbers still may have arbitrary numbers looking like a signal which they are not). These are the same values as the "raw" data below - just "cleaned". The values show a very good correlation to the arrival time  of the XUV pulses in the experiment (see help).
++units: fs (bigger numbers (typically) indicate later arrival times of the electrons).

++desc: Electron bunch arrival time measured  with the BAM  before the undulator (pulse resolved data). This one was newly installed in 2020.  Here the complete bunch train from the FEL is recorded (FLASH1 and FLASH2 pulses). Thus there are values from FLASH 2 in the second part. they may be separated by several "0" values if the reprate is different from 1 MHz ...   - It shows a very good correlation to the arrival time  of the XUV pulses in the experiment (see help).
