Next: Method Up: Image Restorations of High Previous: Image Restorations of High . Astronomical images are commonly taken with the intent of making photometric measurements of objects in the field. For pre-COSTAR HST images, the question then arises: should these measurements be made on the original or on the restored image? When the objects of interest are stellar, we might intuitively expect that higher accuracy will be achieved using the restored image. ...
