2024-09-27 Molecular clouds in the Outer Galaxy identified from the MWISP survey doi:10.57760/sciencedb.13094 en Using the density-based spatial clustering of applications with the noise algorithm, the CO data cubes from the Milky Way Imaging Scroll Painting project were decomposed into a set of discrete molecular clouds. A total of 32,162 molecular clouds are identified, covering the northern Outer Galactic plane (l = [15◦,165◦] and l = [195◦,230◦], and b=[−5.◦25,+5.◦25]). The table includes the basic properties for each molecular cloud. Column 1: cloud number. Columns 2-4: the Galactic coordinates and LSR velocity of the cloud centroid. Column 5: velocity dispersion. Columns 6-8: the Galactic coordinates and LSR velocity of CO emission peak. Column 9: peak main-beam temperature. Column 10: angular area of the cloud. Column 11: total flux of the cloud. Columns 12-13: heliocentric and Galactocentric distance. Columns 14-20: effective radius, excitation temperature, mass, mass surface density, virial parameter, mean H2 number density, internal pressure of the cloud. Column 21: “Y” indicates the cloud is resolved (satisfying the Area≥2.5×2.5 arcmin2 criterion), and “N” indicates the cloud is unresolved. 32,162 12CO molecular clouds that covers the northern Outer Galactic plane8(l = [15◦,165◦] and l = [195◦,230◦], and b=[−5.◦25,+5.◦25]).162 12CO molecular clouds that covers the northern Outer Galactic plane8(l = [15◦,165◦] and l = [195◦,230◦], and b=[−5.◦25,+5.◦25]).
