Notes. Fourier parameters were determined as explained in Sect. 3.1, and Fourier ratios are computed as described in Sect. 3.2. Stars exhibiting long-term trends of υγ were modeled using polynomials, and column ‘poly’ states its degree. NDOF = Nobs − 1 − Nmodel states the number of degrees of freedom of the fit, i.e., with Nmodel = 1 + 2 • NFS + poly the number of model parameters. χ2 has the usual meaning; high values of χ2 indicate unmodeled signals, cf. Sect. 4.3. υγ is the constant term of the fitted Fourier series, cf. Eqs. 2 and 3. Note that υγ does not correspond to the barycentric velocity for SB1 Cepheids. Ap2p is the peak-to-peak RV curve amplitude determined from the Fourier fit. A1 and ϕ1 are the semi-amplitude and Fourier phase of the first harmonic, respectively. Ri1 and Φil are the amplitudes and phase ratios of the i–th harmonic relative to the first (Simon & Lee 1981). Uncertainties for all parameters are provided in the data files as explained in App. C. The full table is available via the CDS.
