application definition, extends NXobject
Description:
This is a application definition for raw data from a generic TOF instrument

Official NeXus NXDL schema to which this file conforms
Obligatory value:
NXtofsingleduration: (required) NX_FLOAT
pre_sample_flightpath: (required) NX_FLOAT {units=NX_LENGTH}
This is the flight path before the sample position. This can be determined by a chopper, by the moderator or the source itself. In other words: it the distance to the component which gives the T0 signal to the detector electronics. If another component in the NXinstrument hierarchy provides this information, this should be a link.

INSTRUMENT: (required) NXinstrument
detector: (required) NXdetector
data[xSize, ySize, nTimeChan]: (required) NX_INT
distance[1]: (required) NX_FLOAT {units=NX_LENGTH}
Distance to sample for the center of the detector
time_of_flight[nTimeChan]: (required) NX_FLOAT {units=NX_TIME_OF_FLIGHT}
polar_angle[nDet]: (required) NX_FLOAT {units=NX_ANGLE}
polar angle for each detector element
azimuthal_angle[nDet]: (required) NX_FLOAT {units=NX_ANGLE}
azimuthal angle for each detector element
SAMPLE: (required) NXsample
MONITOR: (required) NXmonitor
mode: (required) NX_CHAR
Count to a preset value based on either clock time (timer) or received monitor counts (monitor).
Any of these values:
monitor|timerpreset: (required) NX_FLOAT
preset value for time or monitor
distance: (required) NX_FLOAT {units=NX_LENGTH}
data[nTimeChan]: (required) NX_INT
time_of_flight[nTimeChan]: (required) NX_FLOAT {units=NX_TIME_OF_FLIGHT}
