Class SkyFov

java.lang.Object
uk.ac.starlink.ttools.plot2.geom.SkyFov

public class SkyFov extends Object
Characterises a field of view on the sky for presentation to the user. The values in degrees should be rounded in decimal to a level of precision suitable for presentation to the user, given the pixel precision of the known plotting surface. The values are therefore approximate, and may in any case be rather rough depending on the geometry involved (which may not lend itself to description as a cone).
