pPXF stellar line-of-sight velocity (left) and velocity dispersion maps (right) for IZw1 (top) and F14348-1447 (bottom); σ_* are not corrected for instrumental broadening. Contours from HST/F160W images, starting from 3σ levels, equally spaced in steps of 0.5 dex. The IZw1 central pixels have been masked because of the strong continuum and BLR emission, which prevents the detection of stellar absorption features.
