Luminescence (version 0.3.1)

calc_FadingCorr: Apply a fading correction according to Huntley & Lamothe (2001) for a given g-value.

Description

This function runs the iterations that are needed to calculate the corrected age including the error for a given g-value according to Huntley & Lamothe (2001).

Usage

calc_FadingCorr(g_value, tc, age.faded, n.MCruns = 500)

Arguments

g_value

vector (required): g-value and error obtained from separate fading measurements (see example)

tc

numeric (required): time in seconds (time between irradiation and the prompt measurement, cf. Huntely & Lamothe 2001)

age.faded

numeric vector (required): uncorrected age with error in ka (see example)

n.MCruns

integer (with default): number of Monte Carlo simulation runs for error estimation

Value

• A data.frame containing the fading-corrected age is returned.

Function version

0.1.2 (2014-04-13 14:27:43)

Details

The error of the fading-corrected age is determined using a Monte Carlo simulation approach. Large values for n.MCruns will significantly increase the computation time.
