variable-W1 MOS
technical updates

This page distinguishes verified technical products, geometry footprint coverage, and extraction inputs still awaiting recovery; coordinate coverage is not presented as a spectral result.

Current pages

E009–E014

a=0–20′ MOS technical QA

No-fit spectra, exact DS9/mask overlays, and technical gates for five pure variable-W1 annuli.

E015 · I013

a=0–40′ local footprint readiness

ATTTSR/FITS-header/XSA coordinate provenance for 183 unique local OBSIDs, 76 intersecting FoVs, and annulus coverage.

E016

formal annuli + Ring_v7 + XMM FoV

Overlay of E015's 15′ XMM FoV, a=40–112′ formal variable-W1 annuli, and the precise composite regions of Ring_v7.

Current boundary: 76 provenance-resolved pointings yield 100.000% nominal geometry across `a=0–40′`; only 41 intersecting fields retain dual-MOS raw ODF and one has a direct clean seed. Restore/reduce the remaining coordinate-only fields before calling any new annular spectrum complete.
