Scientific paper

We developed a new software program called Limovie to produce light curve plots of occultation events. Limovie converts a video to a light curve for a qualitative analysis of occultation events including those difficult ones with very small magnitude drops. If the video is with time insertion or with times signals recorded, the light intensity data can be outputted with the precise times automatically so that the precise times of the occultation events can be obtained. The high detail of the light curve plots of lunar occultations, especially the grazing ones, can allow the user to estimate the size of the star and the lunar limb profile features by applying Fresnel diffraction patterns to the resulted light curve. Limovie can also be used to analyze the events such as the mutual events of the Galilean satellites where the light intensity varies slowly with time. Limovie is also useful for occultations involving close double stars, allowing measuring the component magnitudes. Limovie is a free program obtainable at: http://www005.upp.so-net.ne.jp/k_miyash/occ02/limovie_en-html.
