Notes. Columns 2–4 give the pulsation period P, the yearly period drift d P∕dT (if known), and the adopted reference epoch for period phasing T0. Column 5 indicates if the target is a clear (single-lined) spectroscopic binary based on its vrad (y) or if there is some vrad scatter (s) that make it a possible SB1 (based on the present data only; other Cepheids in the list are known binaries but with no significant effect on our present vrad time series). In case of a SB1, Col. 6 gives the most recent reference providing the best companion orbital parameters, if any. Columns 7–9 give the total number of spectra Nsp used in this study (all spectrographs included), the corresponding number of distinct observation epochs Nepoch, and the deduced pulsation phase coverage (ϕ cov.). Column 10 gives the detail of the spectrum distribution per instrument for each target. (1) G18a, G18b stand for Gallenne et al. (2019) and Gallenne et al. (2018). (2) H, S, C, F, HM, and HN stand for HARPS, SOPHIE, CORALIE, FEROS, HERMES, and HARPS-North, respectively. Ub and Ur stand for the blue and red arms of UVES.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
