Deprojected azimuthally averaged radial profiles of the ¹³CO J = 6−5 and J = 2−1 transitions and the scaled 0.45 mm continuum in the LkCal5 (left) and HD 169142 disks (right). We note that, in the left-hand panel, the ¹³CO J = 6-5 line intensity is roughly constant in the inner ~30 AU in the LkCal5 disk, whereas the 0.45 mm continuum shows a dust cavity. The intensity outside the MRS of the observations is shown in a lighter shade of the corresponding colors. The position of the star is indicated by the black star in the bottom-left corner, and the beam sizes are indicated by horizontal bars in corresponding colors. Furthermore, the rings in the dust are indicated with the vertical black lines. We note that the MRS of the ¹³CO J = 2−1 line is small compared to the beam size due to the uv taper applied to this data set.
