Indeed I have said that a little side error can be a good thing. You have
quoted me correctly! ;-)
I think you're joking here because I commented that I didn't recommend a
pair of constants for Bowdich Table 15 after you made a post listing "Frank's
constants". I've been thinking about writing all that up again since anomalous
dip is a topic of interest to list members again. My strong sense from the
last run through was that you didn't get my point, so I must have been unclear
on this topic previously (the discussion did sprawl over several months and
one list outage). I was not saying back then that there is a BETTER pair of
constants than the ones in the explanation to Bowditch --I was saying that the
constants are not constant. And furthermore that the variability in these
parameters is generally dependent on a quantity which the navigator cannot
measure, namely, the lapse rate in the lower layers of the atmosphere.
