K-band image of the central region of G85.40-0.00 showing the spatial distribution of the IR-excess sources, believed to be cluster members, listed in Table 2. The signs  ×  refer to those sources with K-band excesses or have H − K > 2 and are too faint to be detected in J, and the signs + refer to those sources with four measured IRAC colours. The 6 cm contours (Urquhart et al. 2009) are superimposed in white. The position of the methanol maser is marked with a yellow square, while the highest contours on the SCUBA 850   μm and MIPS 70   μm maps are shown schematically with long (red) and short (blue) dashed lines, respectively. A colour version of this figure is available in the electronic edition.
