Yeah..
As I understand it from what I've read and fathomed out for myself.

Elevation angle and azimuth are determined by the positional difference between a muon hit on two photographic emulsion plates sandwiched together with an aluminium plate divider. Range/distance cannot be determined, it is an entirely two dimensional process.
A muon travelling entirely through solid masonry will impart less energy than a muon that has travelled partially through free space (a void).
The hard bit is logging all the hit positions and hit intensities. Then processing and calibration.
When that's done a graphic can be produced which is effectively a wide angle view, upward from where the emulsion plates were positioned.
I suspect that they were positioned in the horizontal passage below the ante chamber, giving a view of the entire pyramid above that point. It worked very well in the Bent Pyramid rendering all known chambers and confirming that there are no others.
Looking at the images I'd like to see confirmation that the "Big Void" isn't actually the northern air shaft or a propagation anomaly caused by the GG itself, internal re-reflectance or refraction causing a ghost image when plotted and processed.
Anyways the up side is that it can't selectively make something that IS there NOT render, kinda fail safe, so it confirms that there are no other substantial chambers within the structure other than the suspected "Big Void".
So even if the "Big Void" is spurious, at least they have gained something.
I guess they now have to decide whether the evidence is compelling enough to start drilling.

I'm also interested in Tura limestone at the upper reaches of the QC shafts.
