VizieR Online Data Catalog: SuperCAM CO(3-2) APEX survey in SMC (Saldano+, 2024)

We present a CO(3-2) survey at 6pc resolution in the Small Magellanic Cloud (SMC) obtained with the SuperCAM instrument attached to the APEX telescope. We perform a catalog of 225 molecular clouds in the whole bar of the SMC. We use the CPROPS algorithm to identify the molecular clouds and estimate their main CO parameters. We analyze the scaling relations between the radius, velocity dispersion, luminosity, and virial mass of the SMC clouds, and they are compared with those of other low-metallicity galaxies and other surveys performed in the SMC but using different J-transitions.

Parameters of CO clouds in the SMC are reported. All these parameters, which were obtained by using CPROPS (Rosolowsky et al., 2006PASP..118..590R), are corrected for bias sensitivity and resolution. We provide the APEX data cubes used in this article. Three large regions were observed in the SMC, where the CO emission in the transition J=3-2 was detected. All data cubes are in the antenna temperature unit. We used a beam efficiency of 0.38 to convert the antenna temperature to the main beam brightness temperature unit. These cubes are those given by the automatic procedure developed by the SORAL team, therefore, we recommend performing a new baseline fit as we made for our article (see Sec. 2).
