Abstract
The authors are to be congratulated for an interesting paper sure to stimulate discussion as to the applicability of the Power Spectrum Analysis (PSA) technique in the search for periodicities in astronomical data. I have no real qualms with the bulk of their mathematical analysis, but wish to make some comments on the one application which they deal with, that of the velocity structure (or lack thereof) in the Coma cluster. At my request, the authors have kindly supplied me with a copy of the data set which they have used.
