Description:
This is a deep optical mosaic of the Fornax cluster’s core, covering 1.6 square degrees. The data were acquired with ESO/MPG 2.2m/WFI, using a transparent filter that nearly equals the no-filter throughput and thus provides a high signal-to-noise ratio. Based on an approximate conversion to V-band magnitudes, the unbinned and binned mosaics (0.24 and 0.71 arcsec/pixel) reach a median depth of 26.6 and 27.8 mag/sq.arcsec, respectively.

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.
