In the above paper, erroneous data were obtained for some frequencies and were attributed to equipment instability. However, it is shown in this letter that the "errors" were due to singularities in the parameters being measured, as can be seen by examining the equations involved. Additionally, comments are made with regard to resolving the phase ambiguity in the measurement.
