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 A2max$A_2^{\max }$ (Sect. 2.2) is used to classify galaxies as unbarred (A2max<0.2$A_2^{\max } < 0.2$), weakly barred (0.2A2max<0.4$0.2 \le A_2^{\max } < 0.4$), or strongly barred (A2max0.4$A_2^{\max } \ge 0.4$). 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%.
