Analyse portable CW-OSL measurements

The function analyses CW-OSL curve data produced by a SUERC portable OSL reader and produces a combined plot of OSL/IRSL signal intensities, OSL/IRSL depletion ratios and the IRSL/OSL ratio.

Usage
analyse_portableOSL(object, signal.integral, invert = FALSE,
  normalise = FALSE, plot = TRUE, ...)
Arguments
object

'>RLum.Analysis (required): RLum.Analysis object produced by read_PSL2R.

signal.integral

vector (required): A vector of two values specifying the lower and upper channel used to calculate the OSL/IRSL signal. Can be provided in form of c(1, 5) or 1:5.

invert

logical (with default): TRUE to calculate and plot the data in reverse order.

normalise

logical (with default): TRUE to normalise the OSL/IRSL signals by the mean of all corresponding data curves.

plot

logical (with default): enable/disable plot output

...

currently not used.

Details

This function only works with RLum.Analysis objects produced by read_PSL2R. It further assumes (or rather requires) an equal amount of OSL and IRSL curves that are pairwise combined for calculating the IRSL/OSL ratio. For calculating the depletion ratios the cumulative signal of the last n channels (same number of channels as specified by signal.integral) is divided by cumulative signal of the first n channels (signal.integral).

Value

Returns an S4 '>RLum.Results object.
