"Covariance matrix" of "Probing early parton emissions in heavy ion collisions using the Lund jet plane"

The covariance matrix of the unfolded ratio of the normalised PbPb and pp distributions containing the 12 bins of $ln(1/Δ)$ reported in the paper. The first 7 bins in each axis are from the medium kT band (Figure 3 (left) in the paper), while the last 5 are from the high kT band (Figure 3 (right) in the paper).
