Spectra: Lower Sideband (left) and Upper Sideband (right). Spectra are constructed from all positively weighted data: all times, all baselines. Amplitude units are Jy/beam.

Channel map (left) at frequency of peak emission, 225.75 GHz. Contours are shown at 2,4,6,8 x 10% of peak emission. The vertical color bar on the right extends from image minimum (dark) to image maximum (light). Units are Jy/beam. A full width half maximum beam is shown in blue in the lower left-hand corner. All images have been cleaned down to three times the theoretical noise level. Image sizes extend out to the primary beam's half power points. Integrated-intensity map (right), constructed from s04-24, upper sideband only. Line emission has not been subtracted out. Contours are shown at 1,2,3,4,5,6,7,8,9 x 10% of peak emission. The vertical color bar on the right has units Jy/beam x km/s.
