Class AngScale2

  • public class AngScale2
extends skyview.data.AngScale
    Find an appropriate delta to use for getting grid intervals.

    This subclasses the SkyView AngScale class in order to modify its behaviour slightly. The original implementation is copied from the original skyview source.

    The changes consist of addding some larger values to the *Bigs[] arrays, so that lower crowding values actually yield more sparse grids. That includes values that correspond to no grid lines at all (180/360 degrees for lat/lon).
