branch: master
commit 26372ebca4f2cc2d3f7f82467e6751aeafeedcf2
Author: Mohammad Akhlaghi <mohammad@akhlaghi.org>

    Segment: output SKY_STD HDU now has WCS
    
    Until now, when the SKY_STD HDU Segment didn't have any WCS structure, even
    when it had the same image size as the input.
    
    With this commit, that output now also has the input's WCS in its headers.
    
    This bug was reported by Sepideh Eskdandarlou.
    
    This fixes bug #64915.
