orca.transform.post_process_science

Phase 3 — Post-subband wideband science aggregation.

Runs AFTER all per-subband workers complete. Operates on Lustre.

Steps

  1. Wideband stacking: inverse-variance weighted co-adds across subbands (Red 18–41 MHz, Green 41–64 MHz, Blue 64–85 MHz).

  2. 3-colour PNG composites.

  3. Wideband transient search on stacked images.

  4. Wideband solar system photometry.

  5. Detection gathering (target, transient, solar system CSVs from all bands).

  6. Email summary report.

Ported from ExoPipe/post_process_science.py into the orca package.
