Abstract

The aim of the present paper will be to evaluate analytically the weights needed to express the moments A_2m of the light curves — which constitute the basic quantities from which all elements of the respective eclipsing system can subsequently be evaluated as weighted means of the coefficients a_n of an empirical Fourier cosine series representing the observed light curve. It will, in particular, be shown that the weight coefficients φ_i defining even moments (A₀, A₂, A₄, A₆, …) are expressible in a closed form in terms of simple trigonometric functions.
