An example application of the LETM method. (a) Measured light curves for Fe XXIII, Fe XVIII and Fe XV. (b) The Fe XXIII light curve is shown with the solution of single (L(Fe XXIII)) and twice recursive applications (L(L(Fe XXIII))) of equation (8). (c) The Fe XVIII light curve and L(Fe XXIII) solution are highly correlated, as are the Fe XV light curve and L(L(Fe XXIII)) solution.
