Pattern speeds of selected galaxies.

Galaxy ID	Ω_p(ɀ = 0)	Ω_p(ɀ = 0.5)	Ω_p (ɀ = 1.0)
96765	77.22±0.77	32.59 ±0.95	32.04±1.37
476266	89.30±0.50	43.26±1.74	28.03±1.24
371126	36.54±0.84	44.08±0.61	76.55±0.51

Notes. The pattern speeds for the three galaxies 96765, 476266, and 371126, which exhibit a bar at all three redshifts and undergo major mergers within the redshift range ɀ ≤ 1. The pattern speed is measured in km s⁻¹ kpc⁻¹.
