Context and background knowledge

https://docs.mantidproject.org/nightly/algorithms/NormaliseByCurrent-v1.html

Inputs

Scipp data array

Methodology

It has been applied in https://scipp.github.io/ess/instruments/external/powgen/powgen_reduction.html for POWGEN data stored in a NeXus file.

Outputs

Normalised Scipp data array

Which interfaces are required?

Integrated into reduction workflow, Python module / function

Test cases

Missing

Comments

Blocked:

• The csv files from McStas/GEANT 4 simulations do not contain any information about proton charge
• We do not know yet how the relevant information will be stored in the ESS NeXus file.
