Notes. Column (1): object designation as in Table 1. Column (2): identified complex. Column (3): observed Hα flux. As stated in García-Marín et al. (2009b) and in Rodríguez-Zaurín et al. (2011), typical uncertainties in the absolute flux calibration are between 15% and 20%. Column (4): derived Hα luminosity with no correction for internal extinction, except for IRAS 16007+3743. Column (5): computed equivalent width (EW) from the Hα and EW maps (see text). Column (6): Spaxel with the largest value of the EW. Column (7): ratio of the peak of the EW to the derived EW for the whole complex. Column (8): central velocity dispersion. Column (9): relative velocity with respect to the mass center of the system. Column (10): adopted metallicity for the complex, derived using two different line-ratio calibrators (see text).
