cds-question@unistra.frvariable-starsvisible-astronomymedium-band-photometryradial-velocitySimultaneous photometric (uvbyBeta) and spectrographic observations of SX Phe are described. Analysis of the light and velocity frequency spectra are performed. It is shown that all frequencies detected are harmonics or combinations of the fundamental and first harmonic frequencies. Intrinsic (b-y) and c1 values used in conjunction with a model-atmosphere grid appropriate for a star with [M/H]=-1.0 yields <Teff>=7360K and <logg>=3.90. Standard evolutionary models indicate the mass is 1.13 M_{sun}_ and <Mv> value is +2.9. The radial-velocity data indicate a mean radial velocity of -37km/s and a total range of 38km/s.
