Band 9 continuum (left) and moment 0 maps of ¹³CO J = 6−5 (middle) and ¹³CO J = 2−1 (right) after Keplerian masking in the LkCa15 (top) and HD 169142 (bottom) disks. An asinh stretch is applied to the 0.45 mm continuum for HD 169142 to highlight the outer ring. We note the difference in the emission morphologies for the different panels, especially between the gas and dust. The position of the star is marked with a blue star in the center, and the rings in the continuum are indicated with gray ellipses in each panel. The beam is indicated by the white ellipse in the bottom-left corner of each panel, and a 100 AU scale bar is indicated in the bottom-right corner.
