Three-dimensional view (RA, Dec, and V_LSR) of C₂H₅CN (red), (CH₃)₂CO (green), and HCOOCH₃ (blue) distributions in Orion BN/KL. The C₂H₅CN 25_3,23 − 24_3,22 line at 223 553.6 MHz is shown in red surfaces, the (CH₃)₂CO 17_7,11 − 16_6,10 EE line at 223 775.3 MHz in green, and the HCOOCH₃ 11_4,8 − 10_3,7 A lines at 223 550.5 MHz in blue. The isothermal surfaces are plotted from 15% to 95% in steps of 20% of their peak intensities.
