Caption: Figure 5.

Examples of the reduced high-redshift spectra from our data set. The object at the top is a quasar, while the others are LBGs with Lyα emission. For clarity, the spectra have been smoothed with a 3-pixel top-hat filter. The galaxy at the bottom is among our faintest objects, and has marginally sufficient signal-to-noise in the Lyα forest to contribute to our tomographic reconstruction thanks to an above-average 6 hr of exposure over multiple slitmasks.
