Sub-DLA detected towards J223941.8-294955 at z_abs = 1.825. The spectrum is smoothed with a boxcar average of 1.0 pixel for plotting reasons. The solid red line corresponds to the Voigt profile fit to the sub-DLA with an inferred column density of log N_H   I = 19.84 ± 0.14. Emission is clearly seen in the trough of this absorber which is likely to correspond to the Lyman-α emission from the sub-DLA host.
