[80.03] Reconstruction of SXT Flare Images using the IRIS Method

G. Roumeliotis (Stanford University)

We have developed a novel maximum likelihood method dubbed IRIS (Image Reconstruction with Increased Sampling) for reconstructing images that have been blurred by a known point spread function and recorded on a CCD detector. The IRIS method allows the reconstructed images to be represented on a finer grid than that defined by the CCD detector. We illustrate the method on flare images taken by the Soft X-Ray Telescope aboard the Yohkoh spacecraft. An IDL implementation of the IRIS method is available by sending e-mail to the author at
