Crate nereids_pipeline 

nereids-pipeline

Counts-domain fitting: densities, temperatures and backgrounds of one or more regions, fitted to raw open-beam and sample counts.

Modules

• beam - the beam before the sample, per µs of flight time
• counts_fit - one region or more fitted to raw counts (fit_counts)
• counts_map - patches of pixels fitted as one counts fit (fit_map)
• error - pipeline error types
• open_beam - the beam fitted to the open-beam counts (fit_open_beam)
• pulse_calibration - a pulse calibrated on a foil, as a prior

Modules

beam

The beam before the sample: neutrons per µs of flight time.

counts_fit

The areal densities and temperatures of the materials in one or more regions of the detector, each region’s background and gamma transmission, the sample run’s normalization, the time background, the timing offset, the flight path and the pulse’s numbers, fitted to the counts of an open-beam run and a sample run recorded in the same time bins.

counts_map

Maps of a material’s areal densities and temperature over the detector, fitted as one counts fit whose regions are patches of pixels.

error

Error types for the nereids-pipeline crate.

open_beam

The beam, in neutrons per µs of flight time, fitted to the open-beam counts it produces through the instrument pulse.

pulse_calibration

A pulse calibrated on a foil, carried to experiments as a correlated prior on the pulse numbers the foil fitted.
