The document discusses methods for improving the resolution of solar images degraded by atmospheric effects, including the shift and add (SAA) method and self-deconvolving data reconstruction algorithm (SeDDaRA). SAA involves shifting individual images to align a point spread function before adding them together to improve resolution, but it is difficult to apply to extended objects. The document proposes using self-deconvolution to determine the shifting widths for SAA, then applying SAA again using the self-deconvolved frame as the reference frame.
