Catalog description: Laigle et al. (2016)

Reference for publication: Laigle et al. (2016)
The SPLASH data is included in the COSMOS2015 catalog published in Laigle et al. (2016). The catalog contains Y-band imaging from the Hyper Suprime-Cam as well as IRAC coverage from SPLASH/Spitzer in addition to all the already existing optical bands and new YJHKs images from the UltraVISTA-DR2 survey. The COSMOS2015 catalog contains precise PSF-matched photometry, photometric redshifts and stellar masses for more than half a million of sources (excluding masked area) on the COSMOS field.
To maximize catalog completeness for bluer objects and at higher redshifts, objects have been detected on an ultra-deep χ2 sum of the YJHKs and z++ images by running SExtractor in dual mode (Bertin & Arnouts 1996). The catalog contains about 6 x 105 objects in the 1.5 deg2 UltraVISTA-DR2 area and about 1.5 × 105 in the ''ultra-deep stripes'' (0.62 deg2) at Ks ≤ 24.7 (3σ,3''). The deepest regions reach a 90% completeness limit of 1010 Msun to z = 4.
More information on the COSMOS2015 catalog can be found at the official COSMOS webpage.

SXDS
Catalog description: Mehta et al. (2018)
Catalog download: Catalog (v1.5) and Read-me
Reference for publication: Mehta et al. (2018)
The catalog contains the optical data from the Hyper Suprime-Cam UltraDeep layer in grizY and the IRAC coverage from SPLASH/Spitzer together with multi-wavelength photometry, photometric redshifts, and stellar masses for about 800,000 objects detected over 4.3 deg2, with about 530,000 objects in the Hyper Suprime-Cam coverage of 2.4 deg2. The source detection is performed using a multi-band detection image. The photometry is measured on PSF-homogenized images to have a uniform typical seeing of 0.7'' in in the optical and near-infrared bands.
Additional coverage on the SXDF at various wavelengths from the Subaru Suprime-Cam (Furusawa et al. 2008), UDS, VIDEO, MUSUBI and CFHTLS surveys is also included as well as ancillary radio and X-ray catalogs on the SXDF that are available in the literature.
Photometric redshifts are available for all objects in the catalog computed using LePhare. These photo-z's have been calibrated using spectroscopic data available from the variety of surveys and archival data in the literature.
The catalog is available in a compressed FITS binary table format. The various columns in the catalog are described in the accompanying README.
