Is the error build up due to the increasing apparent diameter of the system as NH gets closer between frames?

The decreasing distance (radial velocity) seems to be considered.
My best guess is, that the shift is caused by the proper motion / transverse velocity (applying the astronomical notions for velocities of stars by replacing the solar system barycenter by New Horizons). For a more accurate modelling the transverse velocity components of Pluto/Charon and New Horizons need to be considered. Previously I've assumed the transverse velocity as zero/negligible. |
