I calculated the R_factor by hand (well, by Excel, really) for the real component of the Fourier transformed spectrum. The analysis was actually carried out using Artemis, and I calculated the R_factor over the fitting range in R. For the real component, this was exactly equal to the R_factor returned from Artemis.
I am surprised that it was numerically identical, but I think Matt explained well enough why the R-factor computed using the real part, the imaginary part, or both would be roughly the same.
