Name
Enter a name for the method.
Unit
Select the desired unit. Push the
button to display the selection list
with the possible units: cps, cpm, Bq, dps, dpm and the display of the
current value.

half-width of the narrowest peak, so that all relevant and possibly existing
overlapping peaks will be covered.
A detailed description of the smoothing feature can be found in chapter
