Line proflies of Hα in the redU arm (top panel), and Hβ in the redL arm (bottom panel) of the UVES spectrum of 2M1115. We note that NC and BC indicate the narrow component and broad component of the total Gaussian fit to the profile, respectively. The flux uncertainties are shown as vertical error bars and represent the weighted standard deviation among the four observations. The velocity was set with respect to the rest-frame wavelength (in air) of the respective lines.
