    • Spitzer IRS Enhanced Products

    Metadata Updated: April 10, 2026

    The Enhanced Products consist of two elements:\n\n(1) A collection of 16,986 low-resolution, merged spectra\n\n(2) A Catalog of extracted source positions, synthetic photometry in several bands, PSF profile widths, and other useful quantities.\n\nThese products were produced starting with the final SSC pipeline (ver. 18.18) bksub.tbl SL and LL spectra. The bksub.tbl spectra were extracted from the nod two minus nod one and nod one minus nod two background-subtracted basic calibrated data, using an aperture that expands linearly with wavelength. The calibrated fluxes are consequently strictly valid only for point sources.
