That's a good point about the log files. I'll rename.

It's not germane to the naming topic raised in this comment, but I don't intend this to be a spectrogram when all is said and done, but a histogram. This is in order to cope with bandwidth over the wire, as well as GCS's inability to cope with large numbers of sample points. This is preventing us from having high resolution of the spectra. Rather than a spectrogram, a better approach is to have the user define output bins, so the user can zoom in on, say, 20 histogram bins in the ROI.
