Table 5
Links to Gaia archive tables for retrieving the pulsation characteristics: period(s), epochs of maximum light (E), peak-to-peak amplitudes, intensity-averaged mean magnitudes, ϕ21, R21, ϕ31, R31 Fourier parameters with related uncertainties, and metallicity computed by the SOS Cep&RRL pipeline for the 9575 Cepheids confirmed by SOS and released in Gaia DR2.

Notes. To facilitate access to the table, we also provide the correspondence between parameter (period(s), E, etc.) and the name of the parameter in the Gaia archive table. (a)The BJD of the epoch of maximum light is offset by JD 2455197.5 d (= J2010.0). (b) Photometric metal abundance derived from the Fourier parameters of the light curve for 3738 fundamental-mode DCEPs with period shorter than 6.3 days (see Sects. 2.1.1 and 4.2).
