Al2O3:C Reader Cross-Talk Analysis

The function provides the analysis of cross-talk measurements on a FI lexsyg SMART reader using Al2O3:C chips.

Usage

analyse_Al2O3C_CrossTalk(
  object,
  signal_integral = NULL,
  dose_points = c(0, 4),
  recordType = c("OSL (UVVIS)"),
  irradiation_time_correction = NULL,
  method_control = NULL,
  plot = TRUE,
  ...
)

Arguments

object: RLum.Analysis or list (required): measurement input
signal_integral: numeric (optional): signal integral, used for the signal and the background. If nothing is provided, the full range is used.
dose_points: numeric (with default): vector with dose points, if dose points are repeated, only the general pattern needs to be provided. Default values follow the suggestions made by Kreutzer et al., 2018.
recordType: character (with default): input curve selection, which is passed to get_RLum. To deactivate the automatic selection set the argument to NULL.
irradiation_time_correction: numeric or RLum.Results (optional): information on the used irradiation time correction obtained by another experiment.
method_control: list (optional): optional parameters to control the calculation. See details for further explanations.
plot: logical (with default): enable/disable the plot output.
...: further arguments that can be passed to the plot output

Value

Function returns results numerically and graphically:
