f(t|tmin,signal)=N.1/τ.exp(-t/τ).[cosh(ΔΓ.t/2)-A_ΔΓ.sinh(ΔΓ/2)].[1+q(1-2ω).(Adir.cos(Δmt)-Amix.cos(Δmt))].Θ(t) conv 1/√2πexp-(t'-t)^2/2σ^2

and obtained the following for q=+1 (red) and q=-1(blue)....

The resultant pdf needs an error function of a complex number (x+iy) which there is no such routine in Root so using the infinite series approximation for complex error function from Abramozitz and Stegun we have written a routine which yileds the folowing results for up to 6 terms of the series summation.
