"The scatterplot shows the pulse height of channel 2 vs channel 3, the histograms show cosmic muon spectra in those channels."

So is the histogram chart x axis nanometers wavelength?
If so, what does the spike at 0 with zero notch at 10 or 20 mean?

Is some of the energy really at effective "wavelengths" below 10 nm?

If the scale is in nanometers, the slope up towards 10nm is more and more UV light.
Would that be coming from ionized air inside the dark box?  Ionized traces of outgassing
circuit materials?

Is the gamma ray energy all in the high high frequency spike at or near zero?
