NeuNorm 2.0

Neutron imaging normalization and time-of-flight (TOF) data processing for ORNL imaging facilities — MARS at HFIR and VENUS at SNS.

NeuNorm 2.0 is a complete, scipp-based rewrite of the library. It provides end-to-end pipelines (TIFF/FITS/event loading, dark/gamma correction, flat-field normalization, TOF binning, resonance detection and Bragg-edge imaging) with HDF5 as the primary output format.

Note

NeuNorm 2.0 is a breaking change from the 1.x series. Code written against the 1.x NeuNorm.normalization.Normalization API will not run unchanged on 2.0. Pin NeuNorm<2 if you depend on the legacy API.
