Distributions of CH3OH and H2O maser spots over the SiO 5–4 integrated maps. The positions of CH3OH masers (Pihlström et al. 2011; Cotton & Yusef-Zadeh 2016) are marked by orange crosses, while the positions of H2O masers are indicated by magenta crosses obtained from Lu et al. (2019a). The green stars denote the reference positions selected for deriving the column densities of the molecules. The red lines in the upper-right corners illustrate the magnetic orientations (Paré et al. 2024) with a resolution of 19.6″.
