3D-HERSCHEL UV-TO-FIR PHOTOMETRIC CATALOGS =========================================== RELEASE: V1.1 DATE: June 15, 2026 AUTHORS ------- McNulty et al. 2026 DESCRIPTION ----------- This release provides UV-to-far-infrared (UV-FIR) photometric catalogs for galaxies in four CANDELS/3D-HST extragalactic fields: COSMOS, GOODS-South, GOODS-North, and UDS. These catalogs extend the UV-to-MIR 3D-HST photometric catalogs (Skelton et al. 2014) with Spitzer/MIPS 24 um photometry and Herschel/PACS+SPIRE far-infrared photometry (70-350 um). Also included are stellar population parameters derived from an emulator trained to reproduce Prospector SED modeling results, fit to both the full UV-FIR photometry and to catalogs limited to UV-24 um. Herschel band coverage by field: COSMOS: 100, 160, 250, 350um GOODS-S: 70, 100, 160, 250, 350um GOODS-N: 100, 160, 250, 350um UDS: 100, 160, 250, 350um If you use these catalogs, please cite: McNulty et al. 2026, ApJ (submitted), arXiv:2602.22384 Whitaker et al. 2014, ApJ, 795, 104 Skelton et al. 2014, ApJS, 214, 24 DOWNLOAD CONTENTS ----------------- This release contains one tar archive per field, plus this README.

SPS Catalog (with Herschel): Stellar population parameters derived from Prospector SED modeling emulator fits to the full UV-FIR photometry. Parameters include stellar mass, SFR, dust attenuation, etc. SPS Catalog (without Herschel): Stellar population parameters derived from Prospector SED modeling emulator fits to photometry limited to UV-24 um. DATA FORMAT ----------- Catalogs are provided in both ASCII and FITS formats. Column descriptions and units are provided in the field-level READMEs contained within each tar archive. VERSION HISTORY --------------- V1.1 June 15, 2026 Initial public release CONTACT ------- For questions regarding this data release, please contact: Seamusjmcn@gmail.com ACKNOWLEDGEMENTS ---------- This work is based on observations taken by the 3D-HST Treasury Program (GO 12177 and 12328) with the NASA/ESA HST, which is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS5-26555. This work makes use of the 3D-HST photometric and grism spectroscopic catalogs (Skelton et al. 2014; Momcheva et al. 2016; Brammer et al. 2012), which are publicly available from the Mikulski Archive for Space Telescopes (MAST) at https://archive.stsci.edu/prepds/3d-hst/. This work is based in part on observations made with the Spitzer Space Telescope, which was operated by the Jet Propulsion Laboratory, California Institute of Technology, under a contract with NASA. Herschel is an ESA space observatory with science instruments provided by European-led Principal Investigator consortia and with important participation from NASA. The Herschel data used in this work were obtained as part of the GOODS-Herschel (PI: D. Elbaz), CANDELS-Herschel (PI: M. Dickinson), PACS Evolutionary Probe (PEP), and HerMES programs.
