F. ; Dickens, R. J. Abstract The set of Fourier coefficients of the RR Lyrae stars in the globular cluster NGC 6171 is presented, based on the observations of Dickens (1970). The Fourier phases and amplitudes are shown to vary smoothly and correlate well with the skewness and the acuteness of the light curve. The fundamental and overtone pulsators follow a smooth relation as these quantities vary, but a change in the slope is apparent when the mode changes. The U, B, and V Fourier parameters show no systematic deviation from the average trend. Phase-phase diagrams can now be compared for NGC 6171, Omega Cen, field RR Lyrae stars, and simple models.
