Continuum-subtracted Hα (black solid line) and [N II] (blue solid line) surface brightness profiles of HaTr 5 along the SE-NW at PA=135° (top) and NE-SW PA=45° (bottom) directions extracted from the high-dispersion SOAR GOODMAN spectra. The continuum emission scaled-down by a factor of four is shown in red, where the location of background stars registered by the slit provide accurate fiducial points. The horizontal thin-dotted line in the bottom panel marks the average value of the Hα surface brightness. The magenta line in the bottom-panel is a synthetic Hα emission line profile broadly describing the observed one (see text). Note that the surface brightness of the [N II] emission line is generally smaller than that of Hα, but at the southeast and southwest nebular edges.
