Spectra extracted from KCWI data with circular apertures as presented in Figure 2. The spectra are fitted by PPXF to extract stellar kinematics. The gray shaded areas are excluded from the fit. The velocity shift (V) is measured relative to the best redshift determined from the prior run with stellar absorption, so it is expected to have a very small value. The rest-frame positions of the Ca II absorption are marked with orange dotted lines. The stellar absorptions are all redshifted relative to the nebular lines and [Fe II] emission, implying that the bulk of the line-emitting gas is outflowing.
