(a) Moment 1 map of ¹³CO (1–0) in the velocity range 6–14 km s⁻¹, shown in color scale. Redshifted emission integrated from 10.5 to 14 km s⁻¹ is shown in yellow contours. Contour levels are [0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9]  ×  25.6 K km s⁻¹. Blueshifted emission integrated from 6 to 9.5 km s⁻¹ is shown in blue contours. Contour levels are [0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9]  ×  10.1 K km s⁻¹. (b) Velocity profile along the dashed line shown in panel (a). The red line is a linear fit. (c) Dust temperature and column density maps derived from Herschel data by V. Könyves et al. (2020). The color image shows the dust temperature map. Contours show the column density map. Contour levels are [0.01, 0.1, 0.2, 0.4, 0.6, 0.8]  ×  5.74  ×  10²² cm⁻². The pink box marks the G205.46-14.56 filament.
