   • Scattered light : caused by the roughness of the XRT mirrors.
   • Current standard software corrects scattered light by deconvoluting the PSF (xrt_deconvolve.pro).
   • Scattered light study by Sota Kashima (ISAS/KGU) was applied to the high corona image of 2022/07/16.
   • high corona studied by Takeda and Boland (2024)
   • Kashima's poster presentation (in Japanese)

4. Request of the new dust map to correct full-Sun images (AT)
   Request of the new dust map to correct full-Sun images (AT)
   

   • Recent XRT full-Sun composite image .
   • To help constructing a new dust map, Al_mesh 2048x2048 images were started to be taken in the post bakeout pointings
     ( sample image movie ).
   • It would be nice if we could have a new dust map by the next eclipse observation on 2024/04/08.
