Notes. (1) Name of the spectral extraction region. The * symbol indicates spectra that were re-binned for the analysis (see Sect. 2). (2) Radius in the galaxy plane. (3) Hα observed wavelength. (4) Rotational velocity in the plane of the galaxy. (5−8) Observed flux of Hα, [N II]6583, Hβ, and [O III]5007 emission lines, respectively, within the 1″ × 2.5″ regions. The flux units are in 10−17 erg s−1 cm−2. The error bars shown in the table include the positioning error (Col. 2), fitting errors (Cols. 3 and 5 to 8), or both (Col. 4) (see Appendix A).
