Wed 14 Apr 2021 05:44:38 PM UTC, original submission:   In version 7.6, WCSLIB has added a new 'wcspcx' function to unscramble the PC+CDELT and CD matrix usage (while taking into account that some distortions like TPV don't work easily with PC+CDELT). We should thus add this function (when the user's WCSLIB has it) to the 'gal_wcs_read_fitsptr' function in lib/wcs.c.	Mohammad Akhlaghi <makhlaghi>
