Nuclear spectrum of Paα extracted in an aperture of 0.3″ in diameter. The dotted vertical lines delimit velocity intervals of 100 km s−1. In red we highlight the emission between −100 and 100 km s−1, and in blue the blue-shifted emission associated with outflowing gas and not including the helium lines, that is between −700 and −300 km s−1.
