Notes. In the top part of the table, the results from Decin et al. (2015) and Cernicharo et al. (2015) are reported, where both teams essentially disagreed on the orbital period P, leading to different orbital speeds. In the second part, we give the corresponding normalization units in cgs. In the last part, the corresponding dimensionless parameter computations are shown.
