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}})
