58 spectra of the HO line at 547.676 GHz observed with MIRO between 10h35 and 14h22 UT on 7 September 2014. This map covers the same observations as in Fig. 2, but with a larger binning of 750 × 510 m. The spectra have been also color coded according to the average background submillimeter continuum level: black: < 3 K, blue: 3−50 K, green: 50−100 K, pink: 100−150 K, and red >150 K. The line is only clearly seen in emission, while above the neck/subsolar region, 2.0 >X> 0.5 km and 1.5 >Y> 0 km The scales are the same for all spectra: –4 to +8 K in T_mB (vertical axis) and –3 to +3 km s^-1 in Doppler velocity relative to the nucleus (horizontal axis).
