Class ImageDBFitsHeaderData

  • public class ImageDBFitsHeaderData
extends Object
    The header data associated with a particular image in the database. It contains the x,y center of the sun location within that image. The radius of the sun in the image. The observed distance to the sun when the image was taken. And the number of arc/sec per pixel in the image.
    For details see: AIA FITS Keywords
