We present the COMBO-17 object catalogue of the Chandra Deep Field South for public use, covering a field which is $31\farcm5$ $\times$ $30\arcmin$ in size. This catalogue lists astrometry, photometry in 17 passbands from 350 to 930 nm, and ground-based morphological data for 63 501 objects. The catalogue also contains multi-colour classification into the categories Star , Galaxy and Quasar as well as photometric redshifts. We include restframe luminosities in Johnson, SDSS and Bessell passbands and estimated errors. The redshifts are most reliable at $R quasars , more generally type-1 AGN, is nearly complete and minimally contaminated at $z=[0.5,5]$ for luminosities above M B = -21.7. Their photometric redshifts are accurate to roughly 5000 km s -1 . Galaxy redshifts are accurate to 1% in $\delta_z/(1+z)$ at $R 24$. The selection of stars is complete to $R \sim 23$, and deeper for M stars. We also present an updated discussion of our classification technique with maps of survey completeness, and discuss possible failures of the statistical classification in the faint regime at $R\ga 24$.

3D-HST: A WIDE-FIELD GRISM SPECTROSCOPIC SURVEY WITH THE HUBBLE SPACE TELESCOPE (2012, background): “Therefore, it is notable that the precision of the continuum-only grism redshifts is still significantly better than has been achieved for surveys using many intermediatewidth photometric filters (e.g., Wolf et al. 2004; Ilbert et al. 2009; Whitaker et al. 2011).”
The Mass Assembly Histories of Galaxies of Various Morphologies in the GOODS Fields (2005, positive): “Large galaxy surveys like DEEP2 (Davis et al. 2002) and COMBO-17 (Rix et al. 2004) are promising in this regard because they contain tens of thousands of galaxies spread over a wide area, although we note that stellar mass studies benefit greatly from spectroscopic redshifts.”
