analyse_TL.MAAD: MAAD protocol for TL dating

Description

Function to estimate the ED in TL dating using the MAAD protocol. It provides an estimation of the palaeodose (Q) and/or the supralinearity correction (I). The equivalent dose (ED) is estimated by the addition of Q and I. See details for more information.

Usage

analyse_TL.MAAD(object, eval.Tmin, eval.Tmax, rejection.criteria = list(testdose.error = 10, paleodose.error = 10), fitting.parameters = list(fit.method = "LIN", fit.weighted = FALSE, fit.use.slope = FALSE, fit.aDoses.min = 0, fit.aDoses.max = NA, fit.rDoses.min  = 0, fit.rDoses.max = NA), plotting.parameters = list(plot.Tmin = 0, plot.Tmax = NA, no.plot = FALSE))

Arguments

object

TLum.Analysis (required): object containing the TL curves used for the ED estimation.

eval.Tmin

integer (required): Temperature ( °C) of the lower boundary for the signal integration.

eval.Tmax

integer (required): Temperature ( °C) of the upper boundary for the signal integration.

rejection.criteria

list (with default): list containing the rejection criteria (in %). See details.

fitting.parameters

list (with default): list containing the fitting parameters. See details.

plotting.parameters

list (with default): list containing the plotting parameters. See details.

Value

The results are plotted using plot_TL.MAAD.The function also provides a TLum.Results containing:

Details

This function estimates the equivalent dose for the thermoluminescence dating with the MAAD protocol. It can provide an estimation of the palaeodose (Q) and the supralinearity correction (I) simultaniously or separately. These are estimated using the growth curve approach (QC) (Aitken, 1985) and the dose plateau approach (DP). Both approaches should provide a similar result. The equivalent dose is estimated by the addition of Q and I The Lx/Tx matrix is estimated using calc_TL.LxTx. The average TL curves for each dose step are estimate using calc_TL.MAAD.average. The plateau test values are estimated using calc_TL.plateau.

Rejection criteria The rejection criteria are:

Fitting parameters The fitting parameters are:

Plotting parameters The plotting parameters are:
