Spectral lines of the considered molecular transitions, for a circular aperture with a radius of 1′′. The black dashed line indicates the zero flux level, the red dashed line the line centre (centered at zero velocity with respect to the velocity of the stellar source). Broad line wings are seen in all four lines, but are particularly apparent for the weaker emission line. Such broad line wings are indicative of the potential presence of a differentially rotating disk.
