The Spitzer Spectroscopic Data Fusion -- Merged Spectroscopic Redshift Catalogs in Spitzer Fields
TLDR
The Spitzer Spectroscopic Data Fusion provides merged spectroscopic redshift catalogs for extragalactic fields, enhancing astronomical data analysis.
Key contributions
- Presents the Spitzer Spectroscopic Data Fusion, a merged spectroscopic redshift catalog.
- Covers fourteen widely studied extragalactic survey fields, building on existing photometric data.
- Merges public catalogs with a 1 arcsec radius, providing a single best redshift per source.
- Serves as a community resource for photometric redshift training, SED fitting, and cross-identification.
Why it matters
This paper provides a crucial, regularly updated dataset for astronomers. It streamlines the use of spectroscopic redshifts, which are fundamental for calibrating photometric redshifts and performing accurate multi-wavelength studies. This resource significantly improves the reliability of extragalactic research.
Original Abstract
I present the Spitzer Spectroscopic Data Fusion, a collection of merged spectroscopic redshift catalogs covering fourteen of the most widely studied extragalactic survey fields. Building on the Spitzer Data Fusion multi-wavelength photometric database, the collection merges several publicly available spectroscopic redshift catalogs within each field using a 1 arcsec matching radius, delivers a single best redshift per source together with provenance and overlap flags, and is available on Zenodo at https://zenodo.org/doi/10.5281/zenodo.6368347 The dataset is regularly updated as new spectroscopic surveys are published. It is intended as a community calibration resource for photometric redshift training, SED fitting, and multi-wavelength cross-identification studies.
