sp_validation: extend to tomography #205
Description
Tracking issue (epic) for extending sp_validation from a single-bin (2D) analysis to a tomographic (multi-redshift-bin) one — the core science upgrade for the UNIONS tomographic round. The input pipeline and the GLASS mocks both need to carry per-bin structure.
The goal
A sp_validation that runs the full validation + inference chain per tomographic bin: the input pipeline reads/splits catalogues by redshift bin, and the GLASS mocks generate consistent multi-bin realizations for covariance and null tests.
Pieces
- Extend input pipeline to tomography #191 — extend the input pipeline to tomography (PR)
- Extend glass mocks to tomography #190 — extend the GLASS mocks to tomography (PR)
- PhotoPipe selection v1 (ppv1) incl. z-band in masking/calibration #229 — PhotoPipe selection v1 (ppv1) incl. z-band (PR Add very basic PhotoPipe selection (including z-band) #187)
Context
Previously grouped under the "Restructuring & tomography prep" milestone (#7) alongside the restructuring. Split out here as its own initiative — the restructuring (#202) is cleanup; this is the feature.

Ooh just wanted to say I can help with this too if you'd like! Also perhaps thinking of integrating the inference with Cosmopipe?

That would be great, I can open a sub-issue. I am working toward providing you with a nice GLASS mock with tomography so you can run some tests.
