Experimental data for more than forty different turbulent boundary-layer flows are tested for consistency with the wall-wake description of the mean-velocity profile. Values for several important profile parameters are obtained by means of a carefully conducted fitting process and the results are tabulated. Effects of pressure gradient are considered, but effects of roughness, mass transfer, three-dimensionality, compressibility, etc. are not. The wall-wake description is found to be quite adequate except for a few cases of flows recovering from strong disturbances. Some problems with instrumentation and experimental technique are documented, and the various flows are ordered according to their probable value for testing the accuracy of present or future analytical methods.
