Red and blue bars represent calculated intensities. Red bars mark peaks uniquely belonging to the \(P\bar{6}2c\) model. Blue bars mark peaks also allowed by the parent hcp unit cell. Spheres mark at what pressures the corresponding Bragg peaks were observed. Spheres are only to demonstrate the statistics of observed peaks, and do not reflect the true d-spacing of those peaks at their observed pressures.
