Azimuthally averaged radial profiles of the dust and CO isotopologue emission observed in the HD 100546 disk (black) together with the fiducial model (orange). The beam is indicated with the horizontal bar in the bottom right corner of each panel. The continuum observations are taken from Pineda et al. (2019; high resolution 0.9 mm continuum), Booth et al. (2024; moderate resolution 0.9 mm continuum), the CO, ¹³CO, and C¹⁸O J = 2–1 transitions are first presented in Pérez et al. (2020) and Wölfer et al. (2024), the CO J = 7–6 transition is presented in Wölfer et al. (2024), and the CO J = 3–2 and C¹⁷O J = 3–2 transitions are presented in Booth et al. (2024).
