(meteorobs) More on video Orionids from Colorado

Hi Marco-

That's something I've considered before, given that my cameras operate 
in a rather different brightness range than visual observers. With 
allsky coverage, my data is very good for meteors brighter than mag 2; 
certainly much better than visual observers can typically provide. But 
the vast majority of the data in the past has been visual, and for much 
dimmer meteors. Obviously, the number of bright events is much lower, 
and statistical noise starts becoming a problem- especially with visual 
reports. Although radar data has started filling in some blanks, I'm 
still generally skeptical of published r-values, and don't think that 
much is known about how they vary with stream position, or whether they 
really provide an accurate description of particle sizes over their full 
range.

Chris
