Distribution of 1.2 mm dust continuum emission toward MC27/L1521F. (a) Both color scale and contours show 1.2 mm dust continuum images obtained by the 7 m array. The lowest contour and subsequent contour step are 3.6 mJy beam⁻¹. (b) Both color scale and contours show 1.2 mm dust continuum images obtained by the 12 m array. The lowest contour and subsequent contour step are 0.3 mJy beam⁻¹. The angular resolutions are given by ellipses in the lower left corner of each panel. Black crosses in each panel represent the position of the Spitzer source.
