I care ;-))

For a streamer hit, the top voltage should not need a super high 
bandwidth but I think the current may.  It rings at some high 
frequency...  So be careful of the bandwidth!

Also, if you could add the raw data files I could play with it in 
MathCad and try to figure out the number of coulombs and stuff to see 
if the integral of amps dt works out and stuff.  I am not clear if 
your computer corrected voltage data was in the graphs or not.  I 
would rather have the corrected data if possible.

I will try to play with this too.  My top voltage is monitored 
remotely, unlike your "dream system", so I really don't have numbers 
there but the waveforms should "look" right.  My tiny sparks are also little...

Cheers,
