The velocity-integrated intensity maps of (a) SiO(2–1), (b) SiO(3–2), (c) SiO(5–4), (d) SiO(6–5), (e) SiO(7–6) at their original spatial resolution. This is zoomed-in at the CND scale. The black and red boxes mark the regions listed in Table 2, where the AGN is marked with the red box. These maps are masked with a 3.0σ threshold after the integration over velocity. The velocity ranges for integration are: SiO(2–1) with [−230 km s⁻¹, 160 km s⁻¹], SiO(6–5) with [−230 km s⁻¹, 151 km s⁻¹], and SiO(7–6) with [−74 km s⁻¹, 230 km s⁻¹], and for the rest is the default [−230 km s⁻¹, 230 km s⁻¹].
