This is up to now done by saving the complete ADC trace of the TOF setup. This is a huge amount of data and needs processing. This has to be performed after the beamtime in close contact to [[Markus Braune>>mailto:markus.braune@desy.de||shape="rect"]] ( responsible for [[OPIS>>url:http://photon-science.desy.de/facilities/flash/photon_diagnostics/opis_spectrometer/index_eng.html||shape="rect"]])
