Excerpt from Absolute Photometry of the Light of the Night Sky: The Zenith Intensity of Haleakala (Latitude N 20. 7°) And at Fritz Peak (Latitude N 39. 9°)The earth-bound Observer not only has to attempt the resolution of the three components but also must contend with the effects of the extinction and scattering of the lower atmosphere. The problem of making the extinction and scattering corrections becomes progressively more difficult as the horizon is approached but, fortunately, zenith observations are not seriously affected.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
