The function provides the analysis routines for measurements on a FI lexsyg SMART reader using Al2O3:C chips according to Kreutzer et al., 2018

```
analyse_Al2O3C_Measurement(object, signal_integral = NULL,
dose_points = c(0, 4), recordType = c("OSL (UVVIS)", "TL (UVVIS)"),
calculate_TL_dose = FALSE, irradiation_time_correction = NULL,
cross_talk_correction = NULL, travel_dosimeter = NULL,
test_parameters = NULL, verbose = TRUE, plot = TRUE, ...)
```

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

calculate_TL_dose

logical (*with default*): Enables/disables experimental dose estimation
based on the TL curves. Taken is the ratio of the peak sums of each curves +/- 5 channels.

irradiation_time_correction

numeric or '>RLum.Results (*optional*):
information on the used irradiation time correction obained by another experiements.
I a `numeric`

is provided it has to be of length two: mean, standard error

cross_talk_correction

numeric or '>RLum.Results (*optional*):
information on the used irradiation time correction obained by another experiements.
If a `numeric`

vector is provided it has to be of length three:
mean, 2.5 % quantile, 97.5 % quantile.

travel_dosimeter

numeric (*optional*): specify the position of the travel dosimeter
(so far measured a the same time). The dose of travel dosimeter will be subtracted from all
other values.

test_parameters

verbose

logical (*with default*):
enable/disable verbose mode

plot

...

further arguments that can be passed to the plot output

Function returns results numerically and graphically:

Description |

`$data` |

you can use the column CT_CORRECTION remove the correction*

**Working with a travel dosimeter**

The function allows to define particular aliquots as travel dosimeters. For example:
`travel_dosimeter = c(1,3,5)`

sets aliquots 1, 3 and 5 as travel dosimeters. These dose values
of this dosimeters are combined and automatically subtracted from the obtained dose values
of the other dosimeters.

**Calculate TL dose **

The argument `calculate_TL_dose`

provides the possibility to experimentally calculate a TL-dose,
i.e. an apparent dose value derived from the TL curve ratio. However, it should be noted that
this value is only a fallback in case something went wrong during the measurement of the optical
stimulation. The TL derived dose value is corrected for cross-talk and for the irradiation time,
but not considered if a travel dosimeter is defined.

**Test parameters**

`TL_peak_shift`

numeric (default: `15`

):

Checks whether the TL peak shift is bigger > 15 K, indicating a problem with the thermal contact of the chip.

`stimulation_power`

numeric (default: `0.05`

):

So far available, information on the delievered optical stimulation are compared. Compared are the information from the first curves with all others. If the ratio differs more from unity than the defined by the threshold, a warning is returned.
