(because 47 + 48 = 95)

Test for clumped isotope equilibrium and estimate carbonate formation temperatures from dual clumped isotope measurements

Formation temperatures are estimated either by direct intersection with the equilibrium curve or by projection on the equilibrium curve following an aribitrary kinetic fractionation slope.

Returns p-values and (statistically correlated) temperature estimates with full error propagation accounting for:

• Arbitrarily correlated analytical errors in Δ₄₇ and Δ₄₈ measurements

• Arbitrarily correlated calibration errors on equilibrium Δ₄₇ and Δ₄₈ laws

• Uncertainty in the kinetic fractionation slope
