VizieR Online Data Catalog: LMT/AzTEC 1.1mm Survey of Mon R2 dense cores (Sokol+, 2019)

We observed Mon R2 with AzTEC (Wilson et al. 2008MNRAS.386..807W), the 144-element 1.1mm bolometer array on the 50-m diameter Large Millimetre Telescope Alfonso Serrano (LMT) in its 32m diameter early science configuration from 2014 November 27 to 2015 January 31. Fourteen fields totaling ~2deg² were chosen based on the Herschel survey of the entire cloud (Pokhrel et al. 2016MNRAS.461...22P) such that we covered the majority of the cloud area found at N(H₂)>3x10²¹cm^-2 along with adjacent, lower column density areas within our rectangular survey areas. In addition to the large area shallow survey, we obtained a deeper LMT/AzTEC 1.1mm survey of selected fields in Mon R2 from 2016 January 22 to 2016 February 25 with the goal of characterizing the low-mass end of the CMF with higher confidence. We selected nine regions, each 5arcmin in diameter, that had relatively low mean column density but exhibited filamentary structure in the Herschel map (Pokhrel et al. 2016MNRAS.461...22P) and had relatively few dense cores detected in our shallow survey. The primary goal of this survey is to provide the first ever census of dense gas cores in the Mon R2 GMC. We adopt a core identification process that is similar to the classic two-dimensional (2D) Clumpfind algorithm (Williams, de Geus & Blitz 1994ApJ...428..693W, Cat. J/ApJ/428/693).
