PPV image of C¹⁸0 (2–1) and DCO⁺ (3–2) gas. Each data point denotes the location and centroid velocity of a Gaussian component and each color refers to a different Gaussian fit. The centroid velocity is shown for the DCO⁺ (3–2) line (in orange), and the green data points represent the brightest component of the C¹⁸0 (2–1) line. The red and blue data points indicate the two lower intensity velocity components. The black circle represents the position of the protostar.
