Table information for 'carsarcs.meta'

General

This table is available for ADQL queries and through the TAP endpoint.

Resource Description: Candidate gravitational arcs in the 37 deg^2 of CFHTLS-Archive-Research Survey (CARS). The data include their post-stamp images, astrometry, photometry (u*,g',r',i'), geometric properties (length, length-to-width ratio, profile curvature, area), and photometric redshifts. The arc candidates were selected booth with an automatic arcfinder, based on a tailored image segmentation and a color selection, and by visually inspecting the survey.
