revcal: Reverse temperature calibration

In japhir/stdsim: Simulation of standard and sample measurements for measurement optimisation for clumped isotopes

Reverse temperature calibration

Description

A clumped isotope temperature calibration in reversed form, where the normal calibration y = a * 10^6 / T_K^2 + b is expressed as a function of T_C: T_C = sqrt((a * 10^6) / (y - b)) - 273.15

Usage

revcal(
  D47,
  slope = 0.0449,
  intercept = 0.167,
  slpcnf = 0.001,
  intcnf = 0.01,
  ignorecnf = FALSE
)

Arguments

D47	The \Delta_{47} value.
slope	The slope of the regression.
intercept	The intercept of the regression.
slpcnf	The confidence of the slope of the regression.
intcnf	The confidence of the intercept of the regression.
ignorecnf	Whether or not to ignore the confidence interval.

Details

Defaults to Bonifacie et al. 2017 \Delta_{47} = (0.0449 ± 0.001 * 10^6) / T^2 + (0.167 ± 0.01)

Value

A tibble with input D47 and estimated Tc value with lower and upper bounds.
