Statistics of the RV-Log relationship.
|1||Good sampling, excellent correlation||13||7.9|
|2||Moderate sampling, good correlation||48||29.0|
|4||Weak signals, no correlation||70||42.4|
|5||Strong Log , weak RV||19||11.5|
|6||Strong signals, no correlation||12||28.6|
|7||Strong signals, anticorrelation||11||26.2|
|8||Strong RV, weak Log||19||45.2|
|9||Strong RV, identified origin||26||–|
Notes. Number of stars in each category NB, for the selected stars (207). The percentages indicate the fraction with respect to 148 for categories 1–5 and 42 for categories 6–8. Category 9 corresponds to a strong RV signal with a known origin (mostly presence of planets). Correlation means between RV and Log time series; weak-strong signals are related to the amplitudes of RV and log , especially on long or median timescales, and not to the average level.
