Application of the Method for Integral Deconvolution of the Case of Occultations of Double Stars
Abstract
The most usual method for the determination of the angular separation ρ and the magnitude difference Δm of the two components is the direct comparison of the observed diffraction pattern with a theoretical model. However, it is possible to use a deconvolution process involving both the derivative of the Fresnel diffraction function for a point-like source, and that of the observed intensity. The authors describe a new method, using the integrated deconvolution process (Froeschlé, Meyer, 1983), in which they determine the variations of the apparent surface of the two sources of a double star while it is being occulted.
