CO(7–6) integrated intensity image at 42′′ resolution (pixel size = 30′′). In our FTS observations, CO(7–6) is one of the most sensitive transitions with the lowest median statistical uncertainty (σ_s,med; Table 1). The SLW and SSW arrays are shown as the blue and green crosses, except the central detectors for the first jiggle observation (SLWC3 and SSWD4) in yellow and orange. The spectra with the statistical signal-to-noise ratio S/N_s (integrated intensity divided by σ_s) > 5 are presented in red (our threshold for detection; Sect. 3.1) and their x-axis (in GHz) and y-axis (in 10^-18 W m^-2 Hz^-1 sr^-1) ranges are shown in the bottom right corner with the spectrum of the pixel observed with SLWC3 and SSWD4. The black dashed circle delineates the 2′ unvignetted field-of-view for FTS observations and almost all pixels are within this field-of-view. Note that we do have a spectrum for every detector and the blank pixels within the SLW coverage in the current image simply result from the rebinning process.
