Fig. 3


Spectra extracted from the five regions (RN, RS, RW, RE, RC) illustrated in Fig. 2. The right panels show a zoom-in on the H 2 1–0 S(1) line, centred at the systemic velocity of PKS B1718–649. The dashed line shows the fit with a single Gaussian component, while the dotted line shows the residuals. In the bottom panel, solid lines indicate the locations of the H 2 1–0 S(0, 1, 2, 3) lines, while dashed and dotted lines show the H 2 2–1 S(1, 3) and [Si vi] and Brγ lines, respectively.
