Scientific paper

A novel method is presented for the timing of an occultation and the determination of stellar diameters, employing the Integrated Deconvolution process to determine the surface variations of the source while it is undergoing occulation. This method, which does not require knowledge of the derivative I-prime(x) and only employs the intensity I(x), leads not only to an accurate timing, but to a value for the apparent speed of the occultation phenomena and a determination of possible angular diameters. The technique is applied to the Alpha Tau occultation observations of Panek and Leap (1980), yielding similar results with improved accuracy.
