If rot the position angle is rotated by the specified number
of degrees and the FITs header is updated appropriately.
The det value is the determinant of the CD matrix.
The telescope scale in arc-seconds/mm is also calculated. It assumes square pixels.
outfile= makes the changes in the specified file instead of overwriting the present one.
exp - prints scale in exponential notation.
rows - flips the WCS sense in rows.
rot= rotates the position angle in degrees (default: 0.0).
scale= changes the scale factor by the ratio (default: 1.0).
dr= and dc= shifts the CRPIX2 and CRPIX1 values in the header by the specified number of pixels.
