This is data accompanying a paper on gravitatioal arcs found in the
CARS survey.  Markus got it via mail and web site
(http://www.ita.uni-heidelberg.de/~maturi/Public/arcs/) directly from the
author, Matteo Maturi <maturi@uni-heidelberg.de> (March 2013)

An update at publication time was again handled by Markus (May 2014)
