Re: [idvusers] Threshold for closed circle in station model?

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, 

Chris Herbster

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,
