Notes. Offsets relative to our reference positions for N113 and N159W (see Figs. 1, 3, and 4). Velocity-integrated flux, ∫ Flux dv, local standard of rest velocity, VLSR, full width at half maximum line width (FWHM), and peak flux (Flux) were obtained from Gaussian fits using CLASS as part of the GILDAS software. For the thermal and non thermal velocity dispersions, σT and σNT, the sound velocity cs, the Mach number
, the kinetic temperature Tkin, and the turbulent temperature Tturb, see Sects. 3.5 and 4.3. Values in parenthesis are uncertainties.
