Notes. Measurements were derived using the regions presented in Fig. 3, as described in the text. Total integrated measurements for H3 were derived using radial profiles (Sect. 4.2.1) here and in the literature. Measurements marked with a ( † ) were excluded from fitting due to sparser uv-coverage.
