Description

ScippNexus currently returns float32 event weights. Does this yield sufficient precision? Do we need to convert to float64 at some point?

Research direction

Start by tracing how ScippNexus produces and consumes event weights, then identify the precision requirements for the neutron-scattering data reduction workflow. Compare the effects of float32 and float64 on relevant results and document whether conversion is needed and where it should occur.
