TL;DR
This study provides deep Ks-band imaging and point source catalogues for 87 southern massive star formation regions traced by methanol masers, aiding in the analysis of embedded stellar clusters.
Contribution
It offers the first wide-field Ks-band imaging and combined infrared catalogues for these star formation regions, facilitating future stellar population studies.
Findings
Generated Ks-band point source catalogues for 87 regions.
Matched Ks-band sources with GLIMPSE data to create combined infrared catalogues.
Provided publicly available data for the astronomical community.
Abstract
We present deep, wide-field, Ks-band (2.14 micron) images towards 87 southern massive star formation regions traced by methanol maser emission. Using point-spread function fitting, we generate 2.14 micron point source catalogues towards each of the regions. For the regions between 10 degrees and 350 degrees galactic longitude and galactic latitude +/- 1 degree, we match the 2.14 micron sources with the GLIMPSE point source catalogue to generate a combined 2.14 to 8.0 micron point source catalogue. We provide this data for the astronomical community to utilise in studies of the stellar content of embedded clusters.
