Class HipsImage

java.lang.Object

skyview.survey.Image

skyview.survey.HipsImage

All Implemented Interfaces:

java.io.Serializable, Component

public class HipsImage
extends Image

This class defines an image gotten by reading a HEALPix image where the pixels are in the nested pixel order. This assumes the FITS structures found in the WMAP data but could be adapted to other orders as needed.
