We have studied the point spread function (PSF) of the Yohkoh Soft X-ray Telescope (SXT) using the pre-launch calibration data. It is revealed from our study that both a careful consideration on the undersampling effect and a proper choice of statistics are indispensable for determining the best fit analytical function for the SXT PSF. We present the results of numerical simulations supporting our approach toward proper handling of the undersampled PSF. Examples of the derived SXT PSF using a limited number of pre-launch calibration data are shown as a case study.

Optical Characteristics of the Soft X-Ray Telescope Aboard Yohkoh : I. Interpretation of the Undersampled Point Spread Function ()

We examine the effects of deconvolution of Yohkoh SXT images using a Blind Iterative Deconvolution algorithm and a modified PSF/noise suppression method. Though the results show clear enhancement of peak intensities in X-ray structures, some critical problems are found during the calculation, which makes it hard to deconvolve the SXT images with general algorithms. The difficulty comes from the undersampling of SXT images, and therefore more detailed consideration is required for the deconvolution.
