Comparison of gas kinematics traced with water masers and thermal emission for source G011.92−0.61. Upper panel: water maser absolute positions (colored dots) and PMs (colored arrows) overlaid on the JVLA Ku- or K-band (as indicated in the top-left corner) continuum map (black contours). Colors denote the maser V_LSR as coded in the wedge on the right side. The dot size scales logarithmically with the maser intensity. All the plotted PMs have S∕N ≥ 3, and their amplitude scale is given on the bottom. The plotted contours of the JVLA continuum are reported below the plot. 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 Cyganowski et al. (2011), using colors to distinguish the red- and blue-shifted flow lobe. Bottom-left panel: adapted from Fig. 1 by Ilee et al. (2016). SMA 1.3 mm continuum (black contours) and blue/red-shifted ¹²CO (3–2) emission. The outflow PA is indicated by the dotted black line. Bottom-right panel: reproduced from Fig. 2 of Ilee et al. (2018) by permission of the American Astronomical Society. Integrated intensity (black contours) and intensity-weighted velocity (colorscale) for the CH₃ CN v8 = 1 J = 12−11 (K = 1,−1) line observed with ALMA by Ilee et al. (2018). The continuous black segment denotes the PA of the V_LSR gradient in the CH₃CN v8 = 1 line.
