资源简介：
We present the first comprehensive catalogs of 13CO clumps from the Milky Way Imaging Scroll Painting (MWISP) project. By developing an equivalent global detection scheme integrated with the FacetClumps algorithm, we successfully extract 71,661 molecular clumps across a high-resolution 13CO data cube spanning 2310 deg2 from the MWISP Phase I survey. To determine accurate distances, we design an automatic hierarchical distance decision method using signal regions as fundamental objects, effectively resolving the kinematic distance ambiguity problem and obtaining reliable measurements for 97.94% of the sample. These extensive catalogs establish a foundation for investigating molecular clump properties, star formation processes, and Galactic evolution.
