Table 4.
Number of instances where the central 68% and 50% confidence intervals do not overlap between components of the 27 125 wide binaries taken from El-Badry et al. (2021).
| Parameter | 68% intervals | 50% intervals |
|---|---|---|
| μ | 3950 (∼14.6%) | 8246 (∼30.4%) |
| A0 | 5531 (∼20.4%) | 9585 (∼35.3%) |
| log10age | 4 (∼0.01%) | 11 (∼0.04%) |
Notes. We give statistics for the distance modulus μ, extinction A0, and log-age. The 50% confidence interval is “smaller” than the 68% interval, so we expect more cases of non-overlap. We restricted the sample to pairs where both components are within 1 kpc and A0 < 5 mag to exclude the spuriously high extinctions.
