The meaning of ZENITH DISTANCE is the angular distance of a celestial object from the zenith measured by the arc of a vertical circle intercepted between the object and the zenith : the complement of the altitude.
The Radiation Sensitivity and Cumulative Sensitivity have also been calculated, assuming a zenith angle attenuation of the form I θ =I θ .cos 2 θ for cosmic ray intensity.doi:10.1007/BF03052623R. P. Kane1. Physical Research Laboratory, Ahmedabad-9 ;U. R. Rao...

* It serves as the direction of reference for measuring the zenith angle, which is the angular distance between a direction of interest (e.g., a star) and the local zenith, relative to the point for which the zenith is defined.
英语翻译Azimuth(方位角) is the horizontal angle measured in a clockwise direction from the plane of the meridian ,which is a line on the mean surface of the earth joining the north and south poles.The bearing(方位) ,which can be measured clockwise or cou

The spectrum of about 6 × 10muons in the zenith angle range θ=68°-82° and the energy range E=1-1000 GeV has been measured by a Kiel-Desy collaboration at Hamburg. The data are represented by a simple form fit which goes as Esec θ for the integral spectrum at very high energies...
We focus on the ambiguity in the measurement of the zenithal angle and propose a general multispectral approach for estimating the appropriate value of this angle. 展开 关键词: Three-dimensional sensing Polarimetric imaging DOI: 10.1364/OL.37.004218 被引量: 8 ...
