Figure 3. Spatial distributions of the 6.7 GHz methanol maser cloudlets in Cep A HW2. The circle size is scaled as the logarithm of peak brightness; its colour corresponds to the local standard of rest velocity scale shown in the wedge. The magenta star marks the Cep A HW2 position (Curiel et al. 2006): RA (J2000)=22h 56m 17.9816s , Dec (J2000)=62d 01'49.572". The ellipse denotes the dust disc emission at 0.9 mm (Patel et al. 2005), and the arrows mark the elongated knot directions at the base of the jet detected at 7.5 mm (Carrasco-Gonzalez et al. 2021).
