The preferred models of relative motions for candidate companions with previous astrometric measurements.
Notes. The Common Proper Motion model (CPM) assumes that the two stars have the same proper motion and parallax; the Background model (BG) is based on the candidate companion being a distant background star with negligible proper motion and parallax. Results significant by more than 1.0σ are highlighted in the table.
NOMAD and PPMXL give significantly different proper motions to UCAC4 for CoRoT-3; the CPM model is preferred at 4.3σ using NOMAD, and at 2.3σ PPMXL proper motions. The results for companion 2 are unchanged.
