Notes. The values for the line frequencies, Einstein A coefficients, and upper energy levels (Eup) are from the Leiden Atomic and Molecular Database: http://home.strw.leidenuniv.nl/~moldata/ (LAMDA; Schöier et al. 2005). (1) Per 0.12 km s−1 channel for SO and per 0.24 km s−1 channel for SiO and SiS. All images are generated with a Briggs robust parameter of 0.5. (2) Extracted from a 0.6″ on-source elliptical aperture with the same position angle as the disk as measured from ALMA observations; e.g. Pineda et al. (2019).
