raw_data_1/monitor_<N>

This is an NXmonitor.

Monitors are numbered from 1; the groups are called monitor_1, monitor_2, and so on.

raw_data_1/monitor_<N>/data

An int32 array with dimensions (number of DAQ periods, number of time channels) containing the histogrammed counts for this monitor.

Attributes:

  • axes:

    • period_index,spectrum_index,raw_time on a neutron instrument

    • period_index,spectrum_index,time_of_flight on a muon instrument

  • long_name: "positron counts" (only written on a muon instrument)

raw_data_1/monitor_<N>/monitor_number

An int32 monitor number.

The raw_data_1/monitor_<N>/monitor_number dataset always has value N.

raw_data_1/monitor_<N>/period_index

This is a NeXus link to raw_data_1/instrument/dae/period_index.

raw_data_1/monitor_<N>/spectrum_index

This is a scalar int32 dataset describing which spectrum this monitor corresponds to.

raw_data_1/monitor_<N>/time_of_flight

This is a NeXus link to raw_data_1/instrument/dae/time_channels_<N>/time_of_flight.
