Photometric Redshifts in the W-CDF-S and ELAIS-S1 Fields Based on Forced Photometry from 0.36 to 4.5 Microns
Abstract
The W-CDF-S and ELAIS-S1 fields will be two of the LSST Deep Drilling fields, but the availability of spectroscopic redshifts within these two fields is still limited on deg2 scales. To prepare for future science, we use EAZY to estimate photometric redshifts (photo-zs) in these two fields based on forced-photometry catalogs. Our photo-z catalog consists of ∼0.8 million sources covering 4.9\u2009deg2 in W-CDF-S and ∼0.8 million sources covering 3.4\u2009deg2 in ELAIS-S1, among which there are ∼0.6 (W-CDF-S) and ∼0.4 (ELAIS-S1) million sources having signal-to-noise ratio (S/N) >5 detections in more than 5 bands. By comparing photo-zs and available spectroscopic redshifts, we demonstrate the general reliability of our photo-z measurements. Our photo-z catalog is publicly available at 10.5281/zenodo.46031780
