Hi Jared,

most of the data you like, I've posted just before. Additional information 
for testing your formula:

wire length = 526.2m
quarter wave resonance ('naked' coil) = 366kHz (measured)
1st harmonic resonance ('naked' coil) = 998kHz (measured)
Resonator self capacitance estimated  = 10.3pF

However the coil is operated with the additional capacitance of
the corona wire. At a wire - coil distance = ~30mm (each side of
the coil), the total capacitance would fit to ~17pF, and I have
the following experimental values for the resonances:

f(kHz)
  284
  826
 1329
 1799
~2300

The 5 glowing zones of the photo have been obtained, with the
driving tank circuit adjusted to 2300kHz. 7 zones can be obtained
with ~3500kHz.

Best regards, Kurt
