Notes. The reference position is RA: 18:14:13.50, Dec: −17:55:47.0 (J2000) for W33 Main. The errors in parentheses for VLSR, Δv (FWHM) and the opacity τ of the NH3(1,1) line are fitting uncertainties, while other errors in parentheses are calculated uncertainties (see Appendix C of Tursun et al. 2020). For the calculation method of the (0,0) column density, see Sect. 3.6.
