Injection recovery tests for S1083 and S1268 (top row) and all planet hosts in M 67 (other rows). The blue data points are injected signals that could be recovered by RVSearch, while the red data points were not recovered when injected into the RV data. The horizontal black dotted lines are at 1 Jupiter mass and at the brown dwarf limit (13 M_J). For detected planets, the location is indicated by the black cross.
