David Burrows implemented a complex math version of transverse Mercator
working from Dozier's equations. On a brief stop in the office today (he's
on vacation), he couldn't remember any errors in Dozier's equations
off-hand. He did mention that he could not make it work out to 90 degrees
from the central meridian as the paper states. I think we ended up limiting
it to 85 or 87 degrees. Next week he'll take a look at  his copy of the
paper to see if he wrote any notes down.
