Data

Selection: all IRS Enhanced Product staring-mode spectra within 2° of Sgr A* (RA 266.404988, Dec −28.936178) in IRSA's irs_enhv211 table — the archive's optimally-extracted, order-merged SL+LL spectra, i.e. the highest reduction level distributed for Spitzer IRS staring-mode observations (no spectral-mapping/mosaic-mode products in this radius). Raw per-source IPAC tables are under data/, one per AOR/target (enh<enhid>.tbl); per-source JSON spectra used by the browser are under specdata/; static preview PNGs under pngs/.

Build

Downloaded and assembled from IRSA via astroquery.ipac.irsa. Self-contained static pages — no server code, one JSON blob embedded per map page, per-source JSON fetched on demand by the spectrum browser.
