AMBER data in the CO first overtone lines obtained in 2008 and 2009. The black and red solid lines represent the data taken in 2008 and 2009, respectively. In the panels b)–h), the scaled spectrum observed on 2009 Jan. 5 is overplotted by the blue solid line to show the asymmetry of the visibilities and differential/closure phases within each line profile. The spectral resolutions given in the panels are the values of the binned data as described in Sect. 2.1. a) Normalized spectra. Two spectra derived from the data taken on 2009 Jan. 5 and 6 are plotted by the red and green solid lines, respectively, while the 2008 spectrum is plotted by the black solid line. b)–d) Visibilities observed on the E0-G0-16 m, G0-H0-32 m, and E0-H0-48 m baselines. e) Closure phase. f)–h) Differential phases observed on the E0-G0-16 m, G0-H0-32 m, and E0-H0-48 m baselines.
