SOAR GHTS 1D spectrum (black thick histogram) with two- Gaussian fit of the [N II] (top) and Hα (bottom) emission lines (thin black line). Individual Gaussian curves are shown in blue and red and the residuals of the fit with a black thin histogram. The systemic velocity of HaTr 5 and J17014-4306, and the velocity of the background nebular emission are marked by vertical solid (Vsys), dashed (VCV), and dotted (Vsky) lines, respectively. The spectral dispersion corresponds to ≃6.4 km s⁻¹ per pixel.
