Outflow model fitted to 6.7 GHz methanol masers in G34.396+00.222 according to the model of Moscadelli et al. (2000). The relevant parameters are listed in Table 3. Left panel: dashed line and white circle trace the outflow axis (x-axis) and the powering source (the cone vertex). The jet is aligned to the observer at the angle of 41° and the opening angle of the outflow is 162°. Because of a projection effect the outflow covers the whole area, and is therefore not marked and the scheme for clarity is presented. Right panel: comparison of obtained data (an × symbol) vs. model (open circles). V_c is the systemic LSR velocity as given in Sect. 4.3.
