title: Images and Physical Properties of 360 Molecular Cloud Structures identified with MWISP 13CO(1-0) data

description: This dataset contains the images and physical property table of 360 molecular cloud structures identified with the Milky Way Imaging Scroll Painting (MWISP) 13CO(1-0) data.The relatively accurate distances were obtained from either the reddened background stars with Gaia parallaxes or associated maser parallaxes, spanning from 0.4 to ~15 kpc.We have used this sample to revisit the velocity dispersion-size relation of molecular cloud structures.There are two files in this dataset: images.pdf and table1.csv. Here we describe their contents.images.pdf shows the integrated intensity maps and average spectra of the identified 13CO structures. Table1.csv is the full version of Table 1 in Feng et al. (2024). It contains the physical properties of the structures. The description of each column is given below:ID: Serial No. of the cloud structure;GLON: deg, Galactic Longitude;GLAT: deg, Galactic Latitude;VLSR: km s-1, centroid velocity;VelDisp: km s-1, velocity dispersion;Reff: pc, effective radius;e_Reff: pc, effective radius uncertainty;surface_density: Solar mass pc-2, mass surface density;MLTE: Solar mass, Mass of the cloud structure;The following columns with a suffix of '_A2' are derived in the N(H2) half-max isophote of each 13CO structure, their meanings are the same as their entire structure analogs shown above.VLSR_A2VelDisp_A2Reff_A2e_Reff_A2surface_density_A2MLTE_A2The following columns with 'D' in their names are associated with the sources used to derive the distances:D: kpc, Heliocentric distance,e_D_lo: kpc, distance uncertaintye_D_hi: kpc, distance uncertaintyDname: Name of the source for distance measurementDref: Reference of the source, the references includes:(1) Reid et al.
