主　　题：eclipse Moon Sun:fundamental parameters 

摘      要：Observations of the sky irradiation intensity in the visible wavelengths during a solar eclipse permit to model the Sun diameter,a key number to constrain the internal structure of our *** this paper,we present an algorithm that takes advantage of the precise Moon topography from Lunar Reconnaissance Orbiter to compute,with a high resolution in time,the geometrical part(***-of-atmosphere,and for a given wavelength)of the sky irradiation at any given location on the Earth during these *** algorithm is also able to model the Baily’s *** give as an application the theoretical computation of the light curve corresponding to the solar eclipse observed at Lakeland(Queensland,North Australia)on 2012 November *** application to real data,with the introduction of atmospheric and instrumental passbands,will be considered in a forthcoming paper.
