Observed radial profiles of CO and millimeter continuum from ALMA observations compared to models with and without a cavity. Left: radial profile of the CO J = 3−2 integrated emission map (red, top), Band 7 continuum (blue, middle), and Band 6 continuum (orange, bottom). The beam size of the observations in the radial direction is illustrated with a black Gaussian profile in the upper left corner. The modeled emission is shown with a dashed line and is normalized to the peak of the observed profile. The best-fitting or fiducial model is shown in cyan, the best-fitting model without a cavity is shown in purple, a similar model to the best model, but with a cavity that is 100 times more depleted in gas, and dust is shown in gray. The position of HH 48 SW is marked with a gray shaded area. Right: 2D maps of the CO J = 3−2 integrated emission (top), Band 7 continuum (middle), and Band 6 continuum (bottom). Images are rotated by 12 degrees so that the disk is aligned horizontally. From left to right: observations, overall best-fitting model, and best-fitting model without a cavity. The beam sizes of the observations are shown in the lower left corner.
