From: Detection of cavities in a salt mine with cosmic muons: expected results and first data
Normalised relative transmission for 60 days of data taking. Left: contributions from the voids at \(-106\) and \(-85\). Middle: contribution due to the voids only at \(-106\). Right: contribution due to voids only at \(-85\). All histograms have a bin size of \(4^\circ \times 4^\circ\).
