Moment 0 and moment 1 maps for the 5_1,4–4_1,3 transition of A-CH₃OH. Top: integrated intensity maps of the high spectral resolution methanol transition at 243.916 GHz (E_u = 49.66 K) for the three components ([−7−0] km s⁻¹ for the −2 km s⁻¹ component, [0–6] km s⁻¹ for the 2.8 km s⁻¹ component, and [6-16] km s⁻¹ for the 9.9 km s⁻¹ component). Contours start at 4σ at every 4σ. The ellipse in the bottom left corner represents the ALMA synthesised beam. Both sources A and B identified by Alves et al. (2019) are indicated as white filled circles. Bottom: velocity field maps of the high spectral resolution methanol transition at 243.916 GHz (E_u = 49.66 K) for the three components.
