A clumped isotope temperature calibration in reversed form, where the calibration $$y = a \times 10^6 / T^2 + b$$ with \(T\) in Kelvin, is expressed as a function of \(T_C\)(in degrees Celsius): $$T_C = \sqrt{(a \times 10^6) / (y - b)} - 273.15$$

)The \(\Delta_{47}\) value.
The slope of the regression.
The intercept of the regression.
The confidence of the slope of the regression.
The confidence of the intercept of the regression.
Whether or not to ignore the confidence of the temperature calibration.
A tibble with input \(\Delta_{47}\) and estimated Tc value with lower and upper bounds.
Defaults to Bonifacie et al. 2017 $$\Delta_47 = (0.0449 \pm 0.001 \times 10^6) / T^2 + (0.167 \pm 0.01)$$
