Maps derived from the VLA NH₃ observations overlaid with the contours of ALMA 1.3 mm continuum emission. (a) Velocity field (moment 1) map of NH₃ (1, 1) main hyperfine line. The northern filament and the southern filament are velocity-coherent. (b) Rotational temperature map. (c) FWHM map of NH₃ (1, 1) main hyperfine line. In all panels, the contours are [3, 5, 10, 20, 40, 80, 160] × σ_rms (σ_rms = 0.10 mJy beam⁻¹). The synthesized beam of 0﹩\mathop{.}\limits^{\unicode{x02033}}﹩68 × 0﹩\mathop{.}\limits^{\unicode{x02033}}﹩58 is shown in the lower left of each panel, and a 0.1 pc scale is in the upper right in panel (c).
