Spectra of the five J = 5–4 (SiO) and J = 6–5 (Si18O) transitions from SiO isotopologue observed with ALMA. The dashed red line is at the systemic velocity of 5.5 km s-1. To guide the readers eyes, we overplotted the 28SiO v = 2 spectrum with three Gaussians of arbitrary width to highlight the three peaks that are due to the SiO emission.
