Sentences with phrase «sources of the false positives»

Results from these tests provide also in many cases insights into the nature of the sources of the false positives, which are generally produced by one of several kinds of configurations involving eclipsing binaries (EB).

Among the undiluted binaries, we note that Brown only mentions grazing binaries as a principal source of false positives; however, as can be seen in Table 2, eclipses among stellar components with large area or surface - brightness ratio (SB1 in Table 2) are the cause of a significant fraction of false positives.

Binary stars provide the primary source of false positives among Kepler planet candidates, implying that false positives should be nearly randomly - distributed among Kepler targets.
