Examples of jsky.coords.CoordinateRadius

jsky.coords.CoordinateRadius
Represents a generic center coordinate and radius range (or width and height), Some methods are provided to check if another coordinate point lies within the range. The coordinates and radius (or width and height) values are treated in a generic way.
