Zodiacal background and Earthshine intensities versus wavelength

Zodiacal contribution assumes an ecliptic latitude of 30 degrees
and an ecliptic longitude of 180 degrees, yielding a V band
surface brightness of 22.7 magnitudes per square arcsec.

Earthshine assumes an angle of 24 degrees between the target
and bright limb of the Earth. This is a relatively high
background configuration. LOW-SKY observations will have
Earthshine backgrounds lower by roughly a factor of 6.

Column 2: Earthshine intensity (in erg/sec/cm^2/Angstrom/arcsec^2)
Column 3: Zodiacal intensity (in erg/sec/cm^2/Angstrom/arcsec^2)
Column 4: Total background intensity (sum of columns 2 and 3)
