2.3.30 Recalculate
Click the Recalculate button on the ArArCALC Toolbar if you want to refresh the age calculations. In most cases, this is not necessary, because ArArCALC automatically recalculates the ages when you make changes. There is one exception, however, that is when you have updated your preferences or irradiation constants (see also: Preferences, Irradiations and Projects). In that case, your new settings will be applied when you hit the Recalculate button or when ArArCALC recalculates because you made other changes to the age calculation file. Examples of the latter are the (un)flagging of your analyses, adding or deleting analyses, changing the 1 or 2 sigma confidence level, changing the age units, etc.
