timed_dataframe has empty values when no electrons are present

[balerion]

Is your feature request related to a problem? Please describe.
when looking at the timed_dataframe, if there were no electrons for a specific pulseID, no other values are saved for any column, even if in principle these values are available in the h5 files

Describe the solution you'd like
I would like the dataframe to contain available values also for pulseIDs that have no electrons

Describe alternatives you've considered
I have not really considered any alternative, but i would be happy to

Currently this is the scope of how the timed df is produced.

dataframe_pulse = dataframe[
            self.multi_index + channels
        ]
dataframe_pulse = dataframe_pulse[
            (dataframe_pulse["electronId"] == 0) | (np.isnan(dataframe_pulse["electronId"]))
        ]

Are you suggesting we provide an option to keep the nans?

i don't think so, but maybe i did not understand your reply fully.
Let me explain my problem better. If during a train of 400 FEL pulses, there is a pulse with no electron counts, then the timed_dataframe has no entries for that FEL pulse. Simply no value, which would actually be available in the original h5 file, is saved in the dataframe. These data would still be of great value, even if no electrons are detected by the dld.
