get_ages: Single-grain FT age FT ages

In tobiste/laftr: Calculates the ages from LA-ICP-MS based fission track dating

Single-grain FT age FT ages

Description

blabla bla

Usage

get_ages(x, rhos, zeta)

Arguments

x	"dataframe" with count of spontaneous fission-tracks. containing U U-concentration, given as ^{238}U/^{29}Ca based on cps (for zircon), ^{238}U/^{43}Ca based on cps (apatite), or ^{238}U in ppm and sU standard deviation of U
rhos	numeric. Spontaneous fission track density
zeta	numeric. Calibration factor based on FCT2 fission-track age standard

Note

You can either use U ratio cps, or U ppm. Whatever you choose for zeta calculation, you must use it for age calculation, too.
