Abstract: | We present the results of a six-square-degree Pleiades survey in I and Z , which is photometrically complete to approximately I KP=19.2 ( I Cou=19.6 in the Pleiades). We remove non-cluster contamination on the basis of proper motions and infrared photometry, and present 339 candidate cluster members, 30 of which are fainter than I KP=17.5, and are thus strong brown-dwarf candidates. |
