Notes. Reg 1 = 5′′/diam.; Reg 2 = 10′′/diam.; Reg 3 = spectrum obtained by co-adding all fibers that cover the [Nii]-Hα emission zone; Reg 4 = 30′′/diam. The last two columns correspond to the lower (towards SW) and upper (towards NE) regions of the elongated structure as observed in the emission-line and ionized gas velocity maps (Figs. 5 and 12). The quoted uncertainties include measurements errors. The colon (:) indicates uncertain value.
