Upper panels: large view (left) and zoom on the water maser kinematics near the YSO (right) for the source G176.52+0.20. In each panel, black contours, and colored dots and arrows have the same meaning as in the upper panel of Fig. 1. The V_LSR scale of the left and right panels is different. The V_LSR gradient traced by the water masers is indicated by a dashed line, using colors to denote the red- and blue-shifted side of the gradient. The dotted arrows labeled LJ give the axis of the collimated ¹²CO outflow observed with the SMA by Fontani et al. (2009), using colors to distinguish the red- and blue-shifted flow lobe. Lower panels: large view (left) and zoom on the water masers near the YSO (right) for the source G236.82+1.98. The V_LSR gradient traced by the water masers is indicated by a dashed line, using colors to denote the red- and blue-shifted side of the gradient. The black dotted arrows labeled LJ (left) and the black dotted line labeled LD (right) denote the orientations of the elongated chain of H₂ 2.2 μm knots and the extinction lane in the J-band image, respectively, observed in proximity of G236.82+1.98 by Varricatt (2012), using the Wide Field Camera mounted on the 3.8 m UKIRT.
