Postage stamps for an example candidate galaxy. The field of view is 10 × 10 arcsec. The large RGB picture shows an HST bvi colour composite made with the scale in each colour channel related to the true total intensity, with an arcsinh intensity scaling relation. This colouring scheme is similar to that described in Lupton et al. (2004). The white circle has a one arcsec radius – typically twice the size of the ground-based seeing disk. Postage stamps for all candidates are compiled in the Appendix.
