Physical properties of molecular structures in the G220 region

The high-resolution and high-sensitivity datasets are provided by the ongoing Milky Way Imaging Scroll Painting (MWISP) project [1]. The cloud structure identification approach, developed by Yan et al. (2020) [2], is based on the density-based spatial clustering of applications with noise (DBSCAN) algorithm.

In total, we identified 1,502 12CO, 570 13CO, and 53 C18O molecular structures and estimated their physical properties, which we present here as a table file.The physical properties listed in the table are as follows: index, name, average LSR velocity and its dispersion, Galactic Longitude and its dispersion, Galactic Latitude and its dispersion, average integrated intensity, peak main-beam brightness temperature, heliocentric distance, effective radius, area, mass, mass surface density, virial mass, virial parameter, spiral arm, emission line, and matching 12CO structure index.
