Description

Executive summary

Offspecular reflectometry workflows requires $R(Q_x, Q_y)$. Support to target this result instead of $R(Q)$ should be added.

Context and background knowledge

Probably needs an interface similar to what exists in SANS.

Inputs

A nexus file containing experiment data, preferably from a polarized experiment.

Methodology

Probably needs an interface similar to what exists in SANS.

Outputs

A 2d data array representing the reflectivity over a $Q_x$, $Q_y$ grid.

Which interfaces are required?

Integrated into reduction workflow

Test cases

None yet, probably talk to reflectometry IDS.

Research direction

Start by reviewing the existing SANS interface and the reflectometry reduction workflow. Discuss the required test cases with the reflectometry IDS team; done means an integrated workflow produces a 2D reflectivity array over a Q_x, Q_y grid from a suitable NeXus file.
