Notes. The value of the parameter is given in bold if fitted. Otherwise, the value is fixed. See text for the definition of the parameters. For the temperatures, we also give the dimensionless electron temperature Θe = kTe/(mec2). We note that the magnetic/gas pressure ratio defined by Eq. (6) is different from the standard plasma-β parameter. The latter is discussed in Eq. (12). We note that the total mass of the torus is ≈10−10 M⊙.
