(Color online) The distortion ξ as a function of temperature T and HS fraction n H and its projections on coordination planes for different values of pressure p. The pressure is increasing as is shown on the right at each figure. The 3D curve (green online) corresponds to the distortion; on the bottom projection n H −T the blue dots correspond to the low-spin state and the red dots correspond to the high-spin state
