Maps of the observed Hα emission obtained from the emission line fit with the best-model (with one or two Gaussian components). The number of components used for the fit in each spaxel is indicated in the right panel. Only spaxels with peak S/N > 3.5 in the Hα line are shown. From left to right: integrated observed flux (not corrected for obscuration), velocity at the peak of the emission, line width W80 (width encompassing 80% of the flux, derived from the total line profile), number of Gaussian components used in the fit. Contours in the flux map show the [20, 40, 60, 80, 90] percentiles; contours in the velocity map start at –150 km s−1 and increase every 50 km s−1; contours in the W80 map are at [200, 300, 400] km s−1.
