a) Very high velocity outflow emission in the ¹²CO J = 6−5 transition overlaid with the SMA ¹²CO J = 2−1 emission (, PA = –14°, Zapata et al. 2009) and the H₂ column density (Peng et al. 2012). The left panel shows the redshifted ¹²CO emission integrated from  +70 to  +100 km s^-1 (V_LSR), and the middle panel shows the blueshifted ¹²CO emission integrated from  −100 to  −70 km s^-1. The ¹²CO J = 6−5 emission is plotted in orange and light blue contours running from 10% to 90% in steps of 10% of the peak intensity. The ¹²CO J = 2−1 emission is plotted in thick red and blue contours from 30% to 90% in steps of 20% of the peak intensity. The H₂ column density (derived from CO isotopologs, Peng et al. 2012) is plotted in gray contours running from 10% to 90% in steps of 10% of the peak density (5.8 × 10²³ cm^-2). The right panel shows the superposition of the high-velocity ¹²CO emission from the left and middle panels, and the beam sizes of APEX and SMA are indicated in the first panel. The squares represent the positions of the outflow explosion center (EC) and the H₂ emission peak 1 and 2. The triangles represent the positions of the Orion HC (south) and BN (north). The stars mark the positions of the five Trapezium stars (θ¹ Ori A, B, C, D, and E). b) The corresponding mean intensities (redshifted and blueshifted) are measured in different position angles (in steps of 45°). Note that the SMA ¹²CO J = 2 − 1 intensities were multiplied by 3.
