In my Feb. 28 posting in answer to Arthur's questions I made a blunder. In
the fourth paragraph I said cosecant and sine instead of secant and cosine.
It should have read:

"She looks bigger according to the ratio of her distance from the earth's
center to her distance from the earth's surface. That ratio is the secant of
her HP. You may want to make a sketch to see why. And in case you don't deal
in secants, the ratio is the inverse of the cosine of HP."

Unfortunately, that statement is not much help in understanding the formula
for calculating augmentation. Better to just forget that paragraph. Sorry.
