Evolution of halo and disk masses, and their characteristic scales for 411321 TNG-TVP as a typical example. From left to right: halo mass M_h, disk mass M_d, Navarro-Frenk-White halo scale parameter b_h, and Miyamoto-Nagai disk-scale parameters a_d and b_d. The solid green lines with dots show the parameters recovered from the IllustrisTNG-100 data. The dotted and dash-dotted blue lines correspond to the values after the interpolation and smoothing with a 1 Myr time-step that was used in the orbital integration.
