Similar to Fig. 1, but for the CO (9–8) line. The FWHM size of the restoring beam is × . The contour levels are [−3, 3, 6, 9, 12, 15, 18, 21] × rmsco, where rmsco = 0.020 Jy beam−1 km s−1. The spectral resolution is 15.625 MHz, corresponding to 32 km s−1. The rms of the spectrum is 0.31 mJy. The CO (9–8) spectral profile is also asymmetric, with enhancement on the red side.
