One more minor point for everyone using my latest formula file. I came across
a problem with symmety specification on a subset of these formula. All the
"HT" varients (which contain the P1/temp term) only exhibit Xaxis or XYaxis
symmetry if the P1 term has a zero imaginary component. Most of the formula
using this are set up for X or XY axis symmetry as the computing time is so
reduced if your along the affected axis. I was mostly using a zero imag
component for these formula and only recently started playing with imaginary
parts and discovered the anomaly. You can use them the way they stand, and you
will always get something interesting, but the symmetry will be forced. This
becomes a problem if you are along an axis with the symmetry turned on and
decide to pan the image a little and recalculate a new strip. It won't always
line up.
