This function estimates the equivent dose in thermoluminescence dating using the SAR protocol.
The equivalent dose is estimated for each disc using the growth curve approaches (QC) (Aitken, 1985) and the dose plateau approach (DP).
Both approach should provide a similar result.
The Lx/Tx matrix is estimated using calc_TL.LxTx.
The plateau test values are estimated using calc_TL.plateau.
Rejection criteria
The rejection criteria are:
recycling.ratio
numeric: Maximum recycling ratio accepted (in %).
recuperation.rate
numeric: Maximum recuperation rate accepted (in %).
paleodose.error
numeric: Maximum error accepted on Lx (in %).
testdose.error
numeric: Maximum error accepted on Tx (in %).
Fitting parameters
The fitting parameters are:
method
character: Fitting method (LIN
, EXP
, EXP+LIN
or EXP+EXP
).
fit.weighted
logical: If the fitting is weighted or not.
fit.rDoses.min
numeric: lowest regenerative dose used for the fitting.
fit.rDoses.max
numeric: highest regenerative dose used for the fitting.
See also calc_TL.SAR.fit.
Plotting parameters
The plotting parameters are:
plot.Tmin
numeric: lowest temperature plotted.
plot.Tmax
numeric: highest temperature plotted.
no.plot
logical: If TRUE
, the results will not be plotted.
See also plot_TL.SAR.
The results are plotted using plot_TL.SAR.
The function also provides an TLum.Results containing:
