Spatial comparison of C₂H₅CN, HCOOCH₃, and (CH₃)₂CO emissions with the same resolution () in Orion BN/KL. The C₂H₅CN 25_3,23 − 24_3,22 line at 223 553.6 MHz is shown in light-red contours. The HCOOCH₃ 11_4,8 − 10_3,7 E/A lines at 223 465.3 MHz and 223 500.5 MHz are combined and shown in light-blue contours. The (CH₃)₂CO 17_7,11 − 16_6,10 EE line at 223 775.3 MHz is shown in thick olive contours. Contours run from 15% to 95% in steps of 10% of their peak intensities, and dashed contours represent − 10% of their peak intensities. The black square marks the center of explosion according to Zapata et al. (2009). The positions of source BN, source I, source n, HC, SMA-1, and IRc6/7 are marked as triangles. The positions of acetone emission peaks (Ace-1 to Ace-3) and some of the methyl formate emission peaks (MF-1, MF-3, MF-8, and MF-9) are marked as stars. Black crosses mark the three NH₃ column density peaks (also close to the temperature peaks) according to Goddi et al. (2011b).
