VizieR Online Data Catalog: The XXL Survey. XLI. GMRT XXL-N 610MHz (Slaus+, 2020)
Abstract
We present the XXLGMRT17_ctpt catalog, drawn and supplementi XXLGMRT17 catalog. This catalog is the result of a cross-correlation process with a multi-wavelength catalogue of the same field by Fotopoulou in prep. All of the counterpart sources were required to have an IRAC 3.6um detection in order to obtain a counterpart catalogue of uniform depth and density. The cross-correlation was performed via Likelihood Ratio method by Sutherland & Saunders, (1992MNRAS.259..413S) and as described in Slaus et al. (this paper). We decided to use a threshold of 0.2 for the Likelihood Ratio value. Multi component sources were matched visually using the MCVCM code (https://github.com/kasekun/MCVCM).
More details about the full XXLGMRT17 catalog, including its verification, reliability, and false detection rate can be found in Smolcic et al. (2018A&A...620A..14S, paper XXIX). More details about the cross-correlation process can be found in the paper. (1 data file).- Publication:
