Fig. 3.

LAE overdensities (δ) found in the HUDF as a function of redshift. The top axis displays the corresponding wavelengths in Å. The noise spectrum is shown in blue on the reverse y-axis. Regions excluded from the overdensity search are displayed in pale blue. The 5800−5966 Å masked region is due to the sodium notch filter used to filter out the light from the bright AO Laser guide star.
