Next: Implementation Up: Image Restorations of High Previous: Technique . This method has been tested on many kinds of data both real and simulated. Here we present three examples in which the structure of the background is of increasing interest and photometry of point sources of diminishing importance. ... Fig. 1 shows the results of this and Fig. 2 shows the photometric accuracy and also a histogram of the background image. ... Fig. 4 shows the quality of the resulting photometry. ...

. This diagram illustrates how a background image may be repeated within the content and padding areas of a box. In this example, a background image is first centered within a box (established by the BODY element of the example). The box contains paragraphs of text, shown in gray to make them discrete. The image, a blue wavy line on a pale yellow background, is then repeated vertically, to the top and bottom of the BODY box. The effect is to create a wavy band down the center of the page. Return to image.

To address the problem of point-source photometry in restored images Lucy (1994) suggested a two-channel photometric restoration method in which the points are represented as functions in one channel and the background, constrained to be smooth by an additional entropy constraint, in the other. ... In the new CPLUCY implementation the stars can be at arbitrary x , y sub-pixel positions but the entropy constraint on the background, used by PLUCY, is retained. ...
