A Catalog of 13CO Clumps from the MWISP in l=10°–20°

The data covers the inner Milky Way within the longitude range 10° < l < 20° and the latitude strip of |b| < 5°.25.The catalog comprising 18,757 molecular clumps was obtained using Facet-SS-3D-Clump, and thecatalog is 90% complete above 37 K km s−1.In the table, columns (2) and (3) are the positions of the clumps in galactic coordinates, and column (4) is the central radial velocity with respect to the local standard of rest (LSR).

Columns (5) and (6) represent the major and minor sizes of the fitted ellipse on the sky plane, respectively. Column (7) represents the FWHM size in the velocity direction. Column (8) is the tilt angle on the sky plane, calculated from the north Galactic pole to the major axis of the clump in the counter-clockwise direction.
