We provide a table of the “high” sky background numbers as plotted in Figure 6.1, for easy reference. See the text and the caption in Figure 6.1 for more details. The high sky values are defined as the earthshine at 38° from the limb and by the high zodiacal light of mV = 22.1 arcsec-2. The contributions of the geocoronal emission lines are tabulated separately in Table 6.5.
