[55.02] The Point Spread Function of the Yohkoh Soft X-ray Telescope

D. E. McKenzie (Montana State University), S. Gburek (Space Research Centre, Polish Academy of Sciences), L. W. Acton, P. C. Martens (Montana State University)

The point spread function (PSF) of the Yohkoh solar observatory's Soft X-ray Telescope has two primary components, a sharply defined core and a diffuse wing due to photon scattering. Because the extent of the PSF is significantly wider than a single pixel, its characterization is useful for improvement of the quality of the SXT images. We will present results from analyses of the two PSF components, and demonstrate our best model of the core and scattering wing of the SXT point spread function. An example of PSF deconvolution to remove the effects of photon scattering will be given.
