Details:

The following command:

$> astcrop --mode=wcs --zeroisnotblank --center=149.58,2.36 --width=0.0945 -h1
calexp-HSC-I-9813-?,?-wide-align.fits --output=output.fits

produces this output

/home/rbaena/.local/bin/astcrop: calexp-HSC-I-9813-7,8-wide-align.fits (hdu
1): has resolution of 4.66667e-05 along dimension 1. However, previously
checked input(s) had a resolution of 4.66667e-05 in this dimension


Different calexp-HSC images (?,?) have different pixel size resolution in the
15th/16th floating decimal in keyflags CDELT1/CDELT2


Before cropping I align images using astwarp. For example:

$> astwarp --align calexp-HSC-I-9813-3,5-wide.fits
--output=calexp-HSC-I-9813-3,5-wide-align.fits
