Galaxy cluster MACS1206 at z ~ 0.44 in a combination of optical filters from the CLASH/HST observations (blue = F435W + F475W, green = F606W + F625W + F775W + F814W + F850LP red = F105W + F110W + F125W + F140W + F160W). We show the strongly lensed multiple images described in Zitrin et al. (2012) for which we have spec-z. Systems 1–3 are highlighted in red, green, and blue, respectively. The image segmentation in these cases has been defined manually to optimize the reliability of the arc photometry. North is up, east is to the left. The pixel flux levels are given by the colour bar.
