    • Spitzer Extragalactic Representative Volume Survey CDFS 2-band Catalog

    Metadata Updated: April 10, 2026

    The "Spitzer Extragalactic Representative Volume Survey" (SERVS) Exploration Science program conducted deep IRAC 3.6 and 4.5 micron observations of five extragalactic fields (ELAIS-N1, Lockman Hole, XMM, ELAIS-S1, and CDFS).\n\nThe 2-band high reliability catalogs are matched [3.6] and [4.5] catalogs, with the low coverage areas near the edges of the survey omitted (POLY_12=1). These catalogs should be used if you are using SERVS to select your sample, as objects in this catalog should be highly reliable (>99.9%). To appear in the catalog objects must appear in both bands, and the detection in one band must be > 10-sigma in CSNR, where CSNR is the coverage-weighted signal-to-noise ratio.
