The disk around the high-mass YSO Bm. Colored dots indicate the peak positions of the most blue- and red-shifted velocity channels for the emission of the nine CH₃ OH (left panel) and seven CH₃CN (right panel) lines listed in Table 2. Colors represent V_LSR as coded on the right of each panel. The dashed black lines, at PA = 18° and 17° for CH₃ OH and CH₃CN, respectively, show the linear fits to the spatial distribution of the channel peaks. The grayscale-filled and black contours represent the JVLA 22-GHz and 13-GHz continuum, respectively, with the same levels as in Fig. 4.
