Notes. - Column (2): $cz_{{\rm nuc, H}\alpha}$ is the H$\alpha $ velocity of the nucleus, defined as the peak of the 6200 Å continuum, except for NGC 7771 where it is refered to the position that makes the velocity field gradient symmetric (see text and Fig. 3c). Column (3): $\Delta v_{{\rm H}\alpha}$ is the H$\alpha $peak-to-peak velocity range over the PMAS FoV. Column (4): $\sigma_{{\rm nuc, H}\alpha}$ is the nuclear H$\alpha $ velocity dispersion (corrected for instrumental effects). All measurements are in km s-1, and are not corrected for inclination and/or angular resolution effects; * for IC 860 $cz_{\rm nuc}$ is from [N  II]$\lambda $6584 and [S  II] $\lambda \lambda $6717,6731. We note that NED quotes a value of $3347~{\rm km~s}^{-1}$ from 21 cm H  I measurements, whereas our value of the velocity is confirmed by measurements of the mid-infrared emission lines with Spitzer/IRS (Pereira-Santaella et al. 2005, in preparation); ** for NGC 7469 the measurements are from [N  II]$\lambda $6584.
