[SBE] curvature of the earth

[Cris Alexander]

I'm not sure what most people do, but I use software for everything,
including the conductivity curves. The FCC provided the algorithm from which
it produced the conductivity curves in the rules, so it wasn't hard to
include them in software. There are some screen shots at:

 That one I know !     ;)

 Most of the analysis is done in software, but the conductivity curves  were
all derived empirically, so that's one that still requires the paper  and a
light table.
