Hey dstndstn, I think I am facing this issue. The website is report -ve parity for an image, while using wcs.fits file, I am getting a +ve parity for the same file. Did you get the answer to this?
Parity is defined as sign(det(CD)), ie, based on the CD matrix of the WCS header.
If you use FITS vs JPEG images, things get confused because of a vertical flip between display conventions in those image formats.
ugh, solve-field reports something different than wcsinfo, and solve-field accepts input in yet another way. and the web site...?
