Figure of the Galaxy showing the region covered by this work. The background image is an artist’s impression of the large structure of the Galactic plane as viewed from the Northern Galactic Pole [courtesy of NASA/JPL-Caltech/R. Hurt (SSC/Caltech)]. The white shaded area indicates the covered region by this work (SEDIGISM+ATLASGAL-GC) with the Galactic Center (GC) region (|ℓ| < 5°) excluded. The white symbol ⊙ indicates the position of the Sun, and the black dots and yellow circles indicate the positions of the total 4120 and the selected 2052 clumps, respectively. The spiral arms are labeled in white and the Galactic quadrants are shown in the corners as Roman numerals.
