Follow-up Comment #7, bug #63171 (project gnuastro):

Nice catch! First I tried --edgesampling but then I thought of smaller CDELT

This debugging image is added as the last HDU if you give the
'--pixelareaonwcs' option to Warp. It is implemented in Library level.

(By the way, how do you guys know what is the image id so you can show them in
your posts? 🤔)

(file #53827, file #53828)
