Velocity channel maps (5, 10, and 15 km s^-1) of the ¹²CO J = 7−6 to J = 6−5 ratio (θ_HPBW = 10″) in the OMC-1 core. The 10 km s^-1 image is overlaid with the ¹²CO J = 6−5 contours as shown in Fig. 1. The empty area are due to data blanking (3 σ level of the ¹²CO J = 7−6 temperature). The dashed-lines indicate that these ratio gradients are likely caused by outflows or filaments. Black triangles mark the Orion Hot Core position.
