XYRATIO
Type: Adverb (Real)
Use: The ratio in coordinate units per pixel separation along the X
axis with respect to the Y axis.
Null value: 0
Null value assignment is usually calculated from the pixel
separations (X to Y increment) given in the image header if the
axes are related (i.e. LL-MM). If the axes are unrelated
(i.e. V-LL), the ratio of the Y to X windows is used (to give
square plot). Some tasks set 0 to 1.4 in such cases. With DOTV
true, the latter case is set to fill one of the two TV
dimensions.
