Sentences with phrase «fraction of false positives»

For the shallower signal we rule out a large fraction of the false positives that might mimic the transits.

This search is contaminated by a large fraction of false positives, caused by different eclipsing binary configurations that might be confused with a transiting planet.

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.

Comparing single - planet candidate KOIs to multi-planet candidate KOIs, we find an observed false positive fraction due to contamination of 16 % and 2.4 % respectively, bolstering the existing evidence that multi-planet KOIs are significantly less likely to be false positives.

We perform numerical simulations to predict the occurrence of astrophysical false positives detectable by the Mission, and quantify the fraction of them that would pass the Kepler candidate vetting procedure.

This statistic measures model performance by plotting the sensitivity values — the true positive fraction of test points — against 1 - specificity — the false - positive fraction for all available probability thresholds [53].
