Notes. We only reproduce 13 lines of this Table here. A full Table with the spectra is available in electronic form at the CDS.
The high uncertainty is caused by the limited wavelength range. In this spectrum there is no continuum on the blue side of the CO absorption line. However, this star is known as IRS 9 and its velocity was measured by Zhu et al. (2008) to −347.8 km s-1.
