To apply Extended Entity Relationship Model (EER) is a good method for representing requirements on information systems, because of its high level of abstraction. Although it is very close to the user, it is not so trivial when some constructs, such as higher order relationships, are used. This paper describes the characterisation and several important results of an experiment performed at our ...

We present Pandora , a new software to model, detect, and characterize transits of extrasolar planets with moons in stellar photometric time series. uses an analytical description the transit light curve for both planet moon front star atmospheric limb darkening it covers all cases mutual planet–moon eclipses during transit. The orbital motion star-planet-moon system is computed high accuracy a...
