View of the CH₃OH maser features detected around G25.65+1.05 (Table A.2). Same symbols as in Fig. 2. The assumed velocity of the YSO is km s^-1 (Sánchez-Monge et al. 2013). The two arrows indicate the direction, and not the actual position, of the red- and blueshifted lobe of the bipolar outflow (°; Sánchez-Monge et al. 2013). The dashed line is the best linear fit of the CH₃OH maser features of group A (PA_CH3OH = −49° ± 7°).
