P is pressure in MPa. Δν₁₀₆₆ is the relative ν₁-CO₃²⁻ Raman shift under pressure, and its value is between 0 and 10 cm⁻¹. The numbers in the brackets indicate the standard deviations (2σ) for the slope and the intercept. The standard errors (MPa) are calculated with the data in Table 1 and the fitting equations in Table 2.
