Contours of high-velocity CO emission plotted in 2 km s⁻¹ wide intervals from a center velocity of 10.5 km s⁻¹ and overlaid on the 8 µm IRAC image in color. HD 37903 is at an offset 0″, 0″. The left panels show high-velocity emission in CO(3−2), and the right panels show this in CO(4−3). The blue- and redshifted velocity ranges for the CO emission are indicated in the top right corner in each plot. The positions of the young stars MIR-63, MIR-62, and MIR-73 are labeled in the top left panel, and the Herbig Haro objects are plotted with black squares. The hatched lines in the CO(3−2) panel for intermediate velocities are drawn to outline the bipolar outflow from MIR-63. The topmost panels show three linearly spaced contours from 0.4 K to 1.1 K in CO(3−2), and from 0.65 K to 1.68 K and 1.125 K in red- and blueshifted CO(4−3), respectively. At high velocities, ± 7.5 km s⁻¹, we plot four contours the from 0.6 K for CO(3−2) and 0.7 K for CO(4−3), with the highest red and blue contours at 2.01 K and 2.41 K for CO(3−2) and 2.12 K and 2.46 K for CO(4−3). For low and intermediate velocities, we plot six contours starting at 0.8 K for both CO(3−2) and CO(4−3) at intermediate velocities, ± 5.5 km s⁻¹, and at low velocities, ±3.5 km s⁻¹. The contours start at 3 K and 2.5 K to avoid contamination from the molecular cloud. For intermediate velocities, the highest contours are at 6.1 K and 6.0 K and 4.9 K and 6.1 K for CO(3−2) and CO(4−3), and for low velocities, they are 11.6 K and 16.3 K and 12.0 K and 15.9 K for CO(3−2) and CO(4−3), respectively.
