G10/COSMOS Data Release
All available datasets for the G10 region

On this page you can download the full G10/COSMOS photometric and spectroscopic catalogues discussed in Davies et al (2015) and Andrews et al (2016, submitted MNRAS). Notes files are also provided, describing the genesis of the catalogues and specific details for each column. CATAID values (column 1) can be used with the G10 cutout tool to obtain data specific to each source. While these catalogue has been checked for errors, if you discover any anomalies please contact . If you wish to receive notification when these catalogues are been updated or new data has been added to the cutout tool, please enter your email address below.


The Davies et al Spectroscopic Catalogue (V04)

This catalogue contains redshift and archival photometric data for all sources in the COSMOS region based on the 2006 catalogue described in Capak et al. (2007) and including the redshift analysis described in Davies et al. (2015). The catalogue covers the ~2deg2 COSMOS region centred at R.A.=150.1191 DEC=2.205749. Source photometry comes from various photometric campaigns in the COSMOS region. The deep broadband observations are described in Capak et al. (2007), which include the HST observations first detailed in Scoville et al. (2007). Also included is photometry from the updated 2008 COSMOS broad- and intermediate-band catalogue, which contains intermediate band Subaru photometry taken from Taniguchi et al. (2007).

In addition to the photometric observations the catalogue also includes the 30-band photometric redshifts obtained by Ilbert et al. (2009) and Laigale et al. (2016) both using the Le Phare photometric redshift fitting code. These use both the broad- and intermediate-band data.

Photometric catalogues are matched to a number of spectroscopic campaigns in the COSMOS region by taking the nearest (on sky) spectroscopic match to a photometric object out to a maximum radius of 2''. Spectroscopic samples used are:

  • zCOSMOS-bright DR3 (Jan 2016) release (Lilly et al., 2009)
  • PRIMUS (Cool et al. 2013)
  • VVDS (Le Ferve et al. 2013)
  • SDSS (Anh et al. 2014)

Lastly, included are all the parameters from the analysis outlined in Davies et al. (2015). This work re-reduces all of the archival zCOSMOS-bright data and assigns automatic redshift classifications using AUTOZ (see Baldry et al., 2014 for details). All sources are then visually inspected to confirm automatic classifications. Final best-fit redshifts are given in the 'Z_BEST' parameter.

The Andrews et al Photometric Catalogue (V05)

This is a total LAMBDAR (Wright et al., 2006) flux catalogue for the G10/COSMOS region. The initial input catalogue was created using SExtractor over the COSMOS Subaru i-band mosaic (Capak et al., 2007, Taniguchi et al., 2007) with the options detailed in Andrews et al. Objects with i < 25 mag were matched to the Davies et al catalogue with a radius of 1arcsec. Problematic SExtractor apertures were identified based on the size-magnitude plane and manually fixed (see the paper for further details). The final catalogue contains 185907 sources.

Photometry was measured using LAMBDAR (v0.12, Wright et al., 2016) and the resulting aperture catalogue with settings described in Andrews et al. LAMBDAR was run on publicly available images from GALEX COSMOS, CFHT, Subaru, UltraVISTA DR2, S-COSMOS G03, SPLASH, PACS Evolutionary Probe DR1 and HerMES DR2. The GALEX and CFHT u images were remosaiced using SWARP. Subaru images had NaN pixels overwritten with a nominal saturation value. Flux cuts and/or prior weighting were applied to the GALEX, IRAC, MIPS, PACS and SPIRE bands with severities corresponding to their resolution and/or sensitivity. These cuts are detailed in Andrews et al.
