Distribution of azimuthal velocity V_ϕ for the low- and high-α samples in the upper and middle panels, respectively. The inner panels show a zoom on the left tail region of each distribution. The bottom panel shows the cumulative distribution of V_ϕ for both samples. The dashed vertical line at V_ϕ = 100 km s⁻¹ indicates the cutoff used to select the Splash population. For the Gaussian fit, we found a mean of 〈V_ϕ〉 = 221 km s⁻¹ and a standard deviation of ﹩{\sigma }_{{V}_{\phi }}=24﹩ km s⁻¹ for the low-α disk, while for the high-α sample, the values are 〈V_ϕ〉 = 181 km s⁻¹ and ﹩{\sigma }_{{V}_{\phi }}=43﹩ km s⁻¹.
