Notes. (a) FWHM is measured with ATLASGAL870 μm continuum by Csengeri et al. (2014). r is derived from FWHM and distance but deconvolved with the beam of ATLASGAL image (19.2′′). See details in Yuan et al. (2017) and Paper I. (b)Distance is taken from Paper I. (c)Clump mass Mclump, H2 column density , and dust temperature Tdust are derived by fitting SED pixel-by-pixel to Herschel 160, 250, 350, 500 μm, and ATLASGAL 870 μm by Yuan et al. (2017) but updated with the new distance by Paper I. (d)
is the beam-averaged H2 column density taken from SED fitting resulted maps with a beam of 36.4′′. (e) Surface density Σ is derived by the clump mass divided by π × r2. The r is the deconvolved radius in the third column. (f) α is the power-law index of H2 column density radial profile
(r) ∝ rα, see details in Paper I. (g)The FWHM line widths for the same pair of sources are taken from the same survey as possible as much. The abbreviation “S-C 18 O” means SEDIGISM C18O J = 2− 1 transition (Structure, Excitation, and Dynamics of the Inner Galactic InterStellar Medium survey, Schuller et al. 2017). “F − 13 CO” and “F-C 18 O” represent FUGIN 13CO J = 1− 0 and C18 O J = 1−0 transitions, respectively (FOREST Unbiased Galactic plane Imaging survey with the Nobeyama 45 m telescope, Umemoto et al. 2017). “H 13 CO+” is MALT90 H13 CO+ J = 1−0 transition (Millimetre Astronomy Legacy Team 90 GHz, Jackson et al. 2013).
