Milky Way Imaging Scroll Painting Data Release 1
Publish Time:2026-08-05
High-quality molecular data is fundamental to the understanding on the distribution, structure and motion of molecular gas, star formation, Milky Way structure, and circulation & interaction between interstellar medium and other components in our Galaxy. During 2011-2022, we carried out a survey of 12CO, 13CO & C18O J = 1-0 along the northern galactic plane (MWISP)，covering the Galactic longitude of 10~230 degrees and the Galactic latitude of +/5 degrees. This data set is the first data release (DR1), including: (1) Summary tables on the survey; (2) FITS data for individual scan unit for all the three lines; (3) The mosaicked cube FITS cubes for all the three lines； (4) A complete cloud catalog defined by 12CO using DBSCAN algorithm, and the catalogs of 13CO and C18O clumps associated with the clouds; (5) Composite color images of the integrated intensities and p-v diagrams; (6) Statistics tables and distribution map of spectral noise; (7) Summary tables of reference positions for each mapping unit; (8) Mwispy, a dedicated python package for processing the MWISP data.
