Spectra of detections of neutral hydrogen in the WVFS cross-correlation with a known optical counterpart. Detections were found using an 5σ threshold and are only accepted if an optical counterpart at a corresponding redshift is cataloged. The central velocity of each object is indicated by the dashed line.
