Fitting the +88 d Hα profile taken with the medium-resolution NOT Gr#17 spectrum (blue). Dashed lines show the individual components: the orange and green lines are Gaussian fits to the broad component and absorption trough, respectively; the red is a Lorentzian profile fit to the narrow emission component, and the purple line represents the underlying continuum. The solid black line shows the composite fit. The inset shows a wider wavelength range revealing the broad wings in Hα. The orange component in the inset has been multiplied by a factor of 3 to more clearly demonstrate its shape. The vertical line marks zero velocity.
