Self-consistent Combined HST, K-band, and Spitzer Photometric Catalogs of the BUFFALO Survey Fields

TL;DR

This paper introduces comprehensive, self-consistent photometric catalogs for over 100,000 sources across six BUFFALO Survey fields, combining multi-band data from HST, Keck, VLT, and Spitzer, with photometric redshifts and publicly available data.

Contribution

The work provides the first unified, multi-wavelength photometric catalogs with improved accuracy and publicly accessible data for the BUFFALO survey fields.

Findings

Catalogs contain over 100,000 sources with multi-band photometry.

Photometric redshifts show 9.2% outlier rate and NMAD of 0.062.

Data is publicly available for community use.

Abstract

This manuscript presents new astronomical source catalogs using data from the BUFFALO Survey. These catalogs contain detailed information for over 100,000 astronomical sources in the 6 BUFFALO clusters: Abell 370, Abell 2744, Abell S1063, MACS 0416, MACS 0717, and MACS 1149 spanning a total 240 arcmin^2. The catalogs include positions and forced photometry measurements of these objects in the F275W, F336W, F435W, F606W, F814W, F105W, F125W, F140W, and F160W HST -bands, Keck-NIRC2/VLT-HAWKI Ks band, and IRAC Channel 1 and 2 bands. Additionally, we include photometry measurements in the F475W, F625W, and F110W bands for Abell 370. This catalog also includes photometric redshift estimates computed via template fitting using LePhare. When comparing to spectroscopic reference, we obtain an outlier fraction of 9.2% and scatter, normalized median absolute deviation (NMAD), of 0.062. The catalogs are publicly available for their use by the community.
