---|---|---|---|
Disks | 609 | 568 | 389 |
Barred | 258 | 285 | 199 |
Strong | 125 | 128 | 79 |
Weak | 133 | 157 | 120 |
Total bar fraction | 0.42±0.02 | 0.50±0.02 | 0.51± 0.02 |
With reliable Ωp | 200 | 251 | 167 |
Notes. Based on galaxies with stellar masses of M* > 1010.0 M⊙. Disks are identified with the selection rules krot ≥ 0.5 and F ≤ 0.7 (Sect. 2.1). The value of (Sect. 2.2) is used to classify galaxies as unbarred (
), weakly barred (
), or strongly barred (
). The total bar fraction is the ratio of the number of barred disks to the total number of disks. Reliable pattern speeds are those with errors of less than 20%.
