Compute uncertainty ellipses for two-nuclides plot

Two nuclides A and B plotted as B/A on the Y-axis and A on the X-axis Return a list with given confidence level ellipses coordinates for each pair of concentrations

tnp_ellipse(Ca, Ca_e, Cb, Cb_e, confidence = 0.98)

Arguments

Ca

Concentration of first nuclide (usually 10Be) (at)

Ca_e

1-sigma uncertainty on the concentration of first nuclide (at)

Cb

Concentration of second nuclide (usually 26Al) (at)

Cb_e

1-sigma uncertainty on the concentration of second nuclide (at)

confidence

confidence level (default 0.98)
