Notes.
Equatorial offsets of the continuum peak with respect to the phase center (see Sect. 2.1). The uncertainties in parentheses represent the standard deviation weighted by the errors given by the 2D-Gaussian fit.
Average deconvolved angular size of the continuum source derived from 2D-Gaussian fits to the ALMA continuum maps. The uncertainty given in parentheses corresponds to the standard deviation.
Distance between the continuum peak position and the position of the closest hot core derived from Fig. 1. The uncertainty given in parentheses is calculated based on the errors given by the 2D-Gaussian fits.
Distance between the continuum peak position and the peak position of the closest UCHII region (Gaume et al. 1995; De Pree et al. 2015). The uncertainty given in parentheses is calculated based on the errors given by the 2D-Gaussian fit.
