Notes. Column 1 provides the source identity. Columns 2–4: are the ellipticity, ϵ, the Position Angle (PA measured north to east) and the semi-major axis, a of the ellipse within which the fluxes were measured, respectively. Column 5 is Hα+[N II] flux measured within the elliptical aperture and the 3σ error. Column 6 is the EW within the ellipse.
