$\begin{figure} \par\includegraphics[width=7.2cm,clip]{7310fig2.eps} \end{figure}$ Figure 2: Relative intensity and position of the centroid of the HCO⁺(1-2) absorption as derived from the fit of a point like-source to the self-calibrated visibilities, for each velocity channel. i) The intensity scale is zero at the continuum level and at -1 for full absorption. The profile of the absorption, as fitted in Fig. 1, is overlaid as a dashed line. ii, iii) Position offsets relative to the centroid of the continuum. iv) Position of the four Gaussian velocity components, compared with the locations of the two lensed images of the quasar (grey disks, not to scale).
