The 12CO and 13CO lines data of 18,190 molecular clouds from the MWISP CO survey

The Milky Way Imaging Scroll Painting (MWISP) is an ongoing unbiased Galactic panel CO survey, which is performed using the 13.7m telescope of PMO and observes 12CO, 13CO, and C18O (J=1-0) lines simultaneously. The detailed introductions for the telescope, the multi-beam receiver system, observation mode, and data reduction procedures are described in Su et al. (2019). The half-power beam width (HPBW) for the telescope at 115 GHz is about 50 arcsec. The velocity separation is about 0.16 km s-1 for 12CO and 0.17 km s-1 for 13CO and C18O lines.We provide the 12CO(1-0) and 13CO(1-0) lines emission data for 18,190 molecular clouds. The 18,190 molecular clouds are identified using the 12CO(J=1-0) line data in the second Galactic quadrant with 104.75 < l < 150.25 degree, |b| < 5.25 degree and - 95 km s-1 < Vlsr < 25 km s-1 from the MWSIP CO survey, using the DBSCAN algorithm (Yan et al. 2021, Yuan et al. 2021). Among the 18,190 12CO molecular clouds, 2,851 12CO clouds have the 13CO molecular gas structures, which are also extracted using the DBSCAN within the boundaries of 12CO clouds (Yuan et al. 2022). The extracted 12CO lines data of 18,190 molecular clouds and the extracted 13CO lines data within the 2,851 12CO clouds are uploaded as the fits files. The corresponding images for each molecular cloud, including the 12CO and 13CO intensity maps integrated along with three different directions (l, b, v) and the averaged spectra of 12CO and 13CO lines, are also added. Two tables containing the parameters of angular areas, velocity span, peak intensities, and integrated fluxes of 12CO and 13CO line emission are also appended. A detailed description of the parameters of the tables is in the Yuan et al. 2021, 2022. In addition, the intensity maps of 12CO(1-0) and 13CO(1-0) emission in the second Galactic quadrant with 104.75 < l < 150.25 degree, |b| < 5.25 degree and - 95 km s-1 < Vlsr < 25 km s-1, which are integrated along velocity and latitude directions, are also uploaded as fits files.
