Crescent Visibility Map Generator / Screen Saver





EHILLE is a tiny analysis tool in form of screen saver drawing the visibility zone of the new crescent on the earth map.

The start date, probability of visibility, processing speed and dwell time between scans can be adjusted. The visibility map for the nearest lunar month is displayed at start. The time and position (latitude/longitude) of the first visibility, together with the hijri date, the real-time values of the moon phase angle and the crescent width are shown. The instantaneous visibility as well as the cumulative visibility can be sketched. Determination of the crescent visibility is based on the Extended Crescent Visibility Criterion.

You can install the screen saver by right-clicking on the SCR-file and selecting "Install". Program parameters are saved in the INI-file.
