H-band SINFONI spectra of LBQS0109 (top) and HB8903 (bottom). The observed spectra (blue lines) are the result of the subtraction between the spectra extracted from the ring-shaped regions (0.5′′ <r< 1′′) and from the nuclear regions (r< 0.5′′). The narrow doublet [Oiii]λ5007 is evident in both sources. The red curves denote the Gaussian fits whose parameters are shown in Table 2. In the smaller inset, the nuclear region (solid black line) and the ring-shaped region (dashed black line) are drawn in the [Oiii]λ5007 velocity maps.
