Brγ channel maps and position velocity diagrams. Prior to extraction all slices with constant wavelength of the datacube were convolved with a Gaussian seeing disk with a FWHM of 0.10 arcsec. Top: channel maps. 21 cm radio contours in gray (.5, 1, 2, and 4 mJy beam-1 with a beam size about four times smaller than our angular sampling) and the white contours are 10%, 25%, 40%, and 55% of the Brγ peak intensity. Velocity ranges are given in km s-1. North is up and east to the left. Bottom: Position velocity diagrams extracted from pseudoslits oriented from east to west. The Y offset is the angular offset of the pseudoslit with respect to the nucleus. Along the pseudoslit, position 0 indicates the position of the continuum peak. Contours represent 10%, 25%, 40%, and 55% of the Brγ peak intensity.

Brγ velocity field derived from single-Gaussian fits to the line profile extracted from every spaxel with continuum contours (20% and 50% of the peak value) in yellow. The inset shows the Brγ velocity field on the nucleus scaled in velocity from −75 km s-1 (blue) to 75 km s-1 (red).
