**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.

Function returns results numerically and graphically:

**slot:** `@data`

Element | Type | Description |

`$data` | `data.frame` | the estimated equivalent dose |

*Note: If correction the irradiation time and the cross-talk correction method is used, the De
values in the table data table are already corrected, i.e. if you want to get an uncorrected value,
you can use the column CT_CORRECTION remove the correction*
