Bob,

Thanks for the info. Your post cleared up a lot of loose ends for me.

Is there any data at all which would indicate the ionization zone might 
trend toward some size relationship to the optical zone? Or is the whole 
business so dynamic, even trends can't be observed?

Thanks,

Larry - W7IUV
