(A) Map of UV brightness integrated from 700 Å to 1800 Å. This figure is the same as Figure 5 apart from integrating over the longer spectral bandpass. We find three regions of “hot pixels” and show the spectra from those regions in the subfigures B–D. (B) The location and spectra of the hot pixel region are consistent with star λ1 Scl. (C) Spectra from three map pixels centered near the location of the hot subdwarf CD−38 222. (D) Spectra from two map pixels showing a broad but mild increase in signal centered near Lyα. The location is consistent with galaxy NGC 300, also known as the Sculptor Pinwheel Galaxy. Note that the Galactic coordinates provided for each spectrum correspond to the location of the Alice boresight at the midpoint of the integration.
