Description

Currently the workflow histograms the data along event_time_offset but we may add one more step to calculate time_of_flight or wavelength.

NMX does not have complicated long pulse profile so we just need to calculate frame unwrapping and use transform coordinates to calculate wavelength from event time offset.

It's not clear where/when exactly this should happen as DIALS also has its own way to figure out the wavelength from the event time offset?
