Integrated intensity maps of Orion-S. The contour levels are in steps of 3.3 for SiO, 2.4 for H13CO+, 3.4 for SO2, 2 for CH3OH, and 3.4 Jy km/s for HC3N. For the 96.7 GHz continuum, contours are in steps of 0.05 starting at 0.1 Jy. The triangle marks the position of the peak continuum (Orion-S); the square marks the position of IRc 2. The beams for each observation are represented in the lower left column of the panel. The molecular line maps have been continuum subtracted.
