Curve integrates a practical Earth Curve and Horizon / Target Calculator that utilises the height of the Observer to provide an accurate calculation of the distance to the Horizon, as well as its declination angle.

The primary screen in this section is a Table that shows the currently saved Curve Calculations sorted by Title. The Navigation Bar shows the number of records, or the number of matches if the Filter Curves option is in use.
