We compare the temperature dependence of the NMR lineshape from 4.2 K to 130 K with predictions based on McMillan's theory, utilizing the recent x-ray diffraction results of Fleming, Moncton, McWhan, and DiSalvo. We employ a theory by Suits to relate the observed lineshape to the alternative theories of the CDW. We confirm McMillan's hypothesis of ""discommensuration""--that the incommensurate CDW is best described by commensurate regions separated by regions of phase slip."
