Basic statistics and main periodicities of the different RV datasets.
| Data set | Nobs | rms RV (m s−1) | dRV (m s−1) | ΔT (d) | δt (d) | Main periodicities (d) |
|---|---|---|---|---|---|---|
| HIRES S0 | 21 | 4.99 | 1.31 | 5185 | 259.3 | 17.3 |
| HARPS-N S1-S6 | 137 | 6.27 | 1.18 | 1864 | 13.1 | 19.1, 18.9, 9.6, 13.4, (18.3) |
| HARPS-N S1 | 27 | 9.99 | 1.35 | 151 | 5.8 | 18.6, 7.6, 14.5 |
| HARPS-N S2-S6 | 110 | 4.94 | 1.14 | 1531 | 14.1 | 9.4, 19.0, 14.4, (18.9) |
| CARMENES S4-S6 | 80 | 4.97 | 1.78 | 780 | 10.0 | 9.3, 18.9, (14.4) |
Notes. dRV refers to the RV uncertainty, ΔT is the total observational timespan, and δt is the mean separation between different epochs. Periodicities are sorted by their occurence in the prewhitening process. After the significant periods (FAP < 0.1%), we show the tentative signals (0.1% < FAP < 1%) in parentheses.
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.
