Stacked profiles for the [CII], NUV, and FIR emission. Top panels: Normalized intensity profiles for the convolved NUV continuum, FIR dust emission, and [CII] line (from left to right) represented by the light blue, red, and orange squares, respectively. In each panel the best fit is shown as a single (dotted line) and a double (solid line) Sérsic function. In this latter case, the central and extended components of the fit with dashed lines are also shown. Bottom panels: Residuals of the fit to the corresponding profile with the single (dotted line) and double (solid line) Sérsic function.
