Azimuthally averaged flux density (in units of [mJy beam−1 km s−1]) as a function of the angular distance from the central star of IK Tau for a selected sample of line transitions. For some transitions, a blend with another line impacts the mean flux density; notes on that can be found in Table A.1. In the upper panel, the error bars designate the scatter w.r.t. the mean flux density (see text for further details); the lower panel displays the normalised mean flux densities, omitting the standard deviations for clarity.
