Derived albedos and diameters based on WISE observations (Grav et al. 2012). The black points show all Trojans for which the WISE-derived albedo uncertainties are 0.02 or lower. The median and 1σ variation of albedo of these Trojans are shown as red horizontal lines. The nine objects shown in red all have WISE-derived albedos and uncertainties that appear to be 3σ or more above the median Trojan albedo. Also shown, in cyan, are three objects measured by WISE to have typical albedos; these targets are used as emissivity calibrators for the survey.
