Maps of the 1.2 to 2.0 mm intensity ratio for SDC18 (top) and SDC24 (bottom) at 20′′ resolution, along with histograms of the pixel values in the regions shown. The contours show the 2.0 mm emission after smoothing to 20′′ resolution, in terms of the S/N, beginning at the SN = 2 level and increasing by a factor of two with each step.
