Links to Gaia archive table to retrieve the pulsation characteristics: period(s), epochs of maximum light and minimum radial velocity (E), peak-to-peak amplitudes, intensity-averaged mean magnitudes, mean radial velocity, ϕ21, R21, ϕ31, R31 Fourier parameters with related uncertainties and metallicity computed by the SOS Cep&RRL pipeline for the 15 021 objects (15 006 Cepheids and 15 stars of different type) released in Gaia DR3.

Notes. To ease table access, we also provide the correspondence between parameter [period(s), E, etc.] and the name of the parameter in the Gaia archive table.
E corresponds to the time of maximum in the light curve and the time of minimum in the RV curve. The BJD of all epochs is offset by JD 2455197.5 d (=J2010.0).
Photometric metallicity based on the Fourier parameters (see Sect. 5.8)
