Comparison of the DM Tau observations (black lines and red circles for SED photometry) and fiducial model (blue lines). Top row: deprojected and azimuthally averaged millimeter-continuum intensity, overall SED, and SED zoomed in on the near-to-mid infrared region. Middle row: deprojected and azimuthally averaged intensity for the moment 0 maps of the ¹²CO, ¹³CO, and C¹⁸O lines. Bottom row: flux integrated over the disk vs. velocity for the ¹²CO, ¹³CO, and C¹⁸O line cubes. The spectral resolution of the observed line cubes is 1 km s⁻¹, while the models are sampled in 0.5 km s⁻¹ steps.
