6.8 Tabular Sky Backgrounds
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 24° from the limb and by the typical zodiacal light of mV = 22.7. Table 6.1 lists the average value of the zodiacal and earthshine backgrounds (excluding the contributions from geocoronal emission lines) in each wavelength interval. The contributions of the geocoronal emission lines are tabulated separately in Table 6.7.
