Chris-
Except for 2.5 which is a single line with no flag, if I read the code
right, it's >= on the low side and < on the high side (as you have it
below).

Julien,
So would "10" be >=7.5 and < 12.5 and then >=12.5 and < 17.5 for "15"?
I guess the question is, "which edge gets the "=" sign for inclusion in the
binning?" I assume the break points are included on one edge. (There I go again, making more
assumptions! )
Thanks for your help,

Subject: Re: [idvusers] Threshold for closed circle in station model?
Professor Herbster,
We've been burned ourselves :-)
My notes say:
- a circle for calm winds (0 speed)
- a shaft with no barbs<= 2.5 knots
- a shaft with a half barb for > 2.5 and< 7.5 knots
Please let us know if you have further questions.
Best Wishes,

Hi folks,
Before I attempt to look through code that I don't know (in a language
I can barely read), can anyone help with a definitive answer to the
thresholds used to draw a "calm" circle around a station, a shaft with
no barbs, and then the 5 knot increment for the barbs? (I assume that
a "short barb" for "5 kts" is drawn is speed is >2.5 kts and <= 7.5,
but I have gotten burned by an assumption more than once in the past!)
As always, any help is welcome!
Thanks,
Chris Herbster
