Query

Search the SPAM catalog by ID, position, uploaded source list, or a SQL-style query on redshift and magnitude. Each match shows photometry, photo-z, and a bio plot with the best-fit and low-z model spectra.

Note on precision:query values are rounded for fast in-browser search — per-filter queries use the native catalog flux to 4 significant figures (derived mag/S/N/color match the catalog to ≲10⁻³; colors use a 1σ upper limit where S/N<1); redshifts, M_UV, β and sizes to 3–4 decimals. Use the FITS catalog for full-precision, science-grade values. See “field definitions” below for the per-quantity detail.
