[Ifeffit] E0 problems

Hello,
I am having some trouble with a first shell fitting. I have good reason to
believe that the compound crystal structure should be quite similar to the
starting input structure from other reliable analysis. The closest neighbor
paths V-O is 1.61 A away so I set R to 0.8 as a start. I summed what I
think are pertinent paths together and tried to fit these paths to a first
shell. The bmp file attached contains the fit, summed paths, and the data
all in R-space. The fit comes away with a small amplitude, huge E0 of close
to -21 eV and negative delr & ss. I have included the artemis project. Is
the k-space any indication that the data is too noisy? Any suggestions and
or questions would be greatly appreciated.
Thank you all,
