Abstract

We present deep, wide-field, Ks-band (2.14-μm) images towards 87 southern massive star formation regions traced by methanol maser emission. Using point-spread function fitting, we generate 2.14-μm point source catalogues (PSCs) towards each of the regions. For the regions between 10° < l < 350° and |b| < 1, we match the 2.14-μm sources with the GLIMPSE point source catalogue to generate a combined 2.14- to 8.0-μm point source catalogue. We provide this data for the astronomical community to utilise in studies of the stellar content of embedded clusters.
