... which ought to be the same as taking the residual of chi(R).  
What's typically plotted (with Artemis and everywhere else) is
|chi(R)|.  When plotting the magnitude like this and selecting "show
residual", the magnitude of the residual is shown:
|chi_data(R)-chi_fit(R)|, not the invidiual differences of real and
imaginary components.
