ess.reduce.time_of_flight.eto_to_tof.monitor_time_of_flight_data(monitor_data, lookup, ltotal, pulse_stride_offset)[source]#

Convert the time-of-arrival data to time-of-flight data using a lookup table. The output data will have a time-of-flight coordinate.

Parameters:

da – Raw monitor data loaded from a NeXus file, e.g., NXmonitor containing NXevent_data.
lookup (time_of_flight.types.TimeOfFlightLookupTable (scipp.DataArray)) – Lookup table giving time-of-flight as a function of distance and time of arrival.
ltotal (MonitorLtotal[TypeVar(RunType, nexus.types.BackgroundRun (int), nexus.types.EmptyBeamRun (int), nexus.types.SampleRun (int), TransmissionRun[nexus.types.SampleRun (int)], TransmissionRun[nexus.types.BackgroundRun (int)], nexus.types.VanadiumRun (int)), TypeVar(MonitorType, nexus.types.Monitor1 (int), nexus.types.Monitor2 (int), nexus.types.Monitor3 (int), nexus.types.Monitor4 (int), nexus.types.Monitor5 (int), nexus.types.Monitor6 (int), nexus.types.IncidentMonitor (int), nexus.types.TransmissionMonitor (int), nexus.types.FrameMonitor (int), nexus.types.FrameMonitor (int), nexus.types.FrameMonitor (int), nexus.types.FrameMonitor (int), nexus.types.CaveMonitor (int))]) – Total length of the flight path from the source to the monitor.
pulse_stride_offset (time_of_flight.types.PulseStrideOffset (types.int | None)) – When pulse-skipping, the offset of the first pulse in the stride. This is typically zero but can be a small integer < pulse_stride.

Return type:
