Projections of fitted angular distribution in background bins
These plots show the comparison between the projections of the data (error bars) and the fit (histograms)
for low-mass background (below the ϒ(1S) peak) and high-mass background (above the ϒ(3S) peak).
The prompt component is in black and the displaced component is red. These projections are done for angular
variables in the Collins-Soper frame.
