Type: Adverb  (Real)
Use:  The ratio in coordinate units per pixel separation
      along the X axis with respect to the Y axis.

      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).

      the Y to X windows is used (to give square plot).
