9.7 Tabular Sky Backgrounds

We provide Table 9.6 of the “high” sky background numbers as plotted in Figure 9.1. See the text and the caption in Figure 9.1 for more details. These high sky values are defined as the earthshine at 38° from the limb and the high zodiacal light of mv = 22.1 magnitude/arcseconds2.
