Top: Example spectrum extracted from one of the selected Voronoi bins. The blue shaded histogram represents the observed flux. Shown in purple is the main Lyα component, in red the redshifted emission, in magenta the total combined emission and in black the absorption components. The vertical red and purple markings denote the emission component centroids. The orange histogram represents the total model, combining emission and absorption. Bottom: Fit residuals presented in the blue shaded histogram. The horizontal dashed orange lines represent the noise thresholds.
