Notes. (a)The reference position is α2000 = 18h47m36s.900 and δ2000 = −02°01′05″.025 (see Sec. 3). (b)Pl and χ are the mean values of the linear polarization fraction and the linear polarization angle measured across the spectrum, respectively. (c)The best-fitting results obtained using a model based on the radiative transfer theory of methanol masers for Γ + Γν = 1 s-1 (Vlemmings et al. 2010; Surcis et al. 2011b). The errors were determined by analyzing the full PDF. (d)The angle between the magnetic field and the maser propagation direction is determined using the observed Pl and the fitted emerging brightness temperature. The errors were determined by analyzing the full PDF. The boldface indicates that |θ+ − 55°| < |θ−− 55°|, i.e., the magnetic field is parallel to the linear polarization vector (see Sect. 4).
