Continuum emission of MWC 349A at 1.4 mm in Band 6 (panel (a)) and 0.87 mm in Band 7 (panel (c)) obtained with ALMA. Color indicates intensities in Jy beam⁻¹, and the ellipse at the lower left corner marks the synthesized beam. The two overlaid points in panels (a) and (c) correspond to the two ends of the disk as seen in the maser distribution for that band. Panels (b) and (d) are zoomed-in areas of panels (a) and (c), respectively.
