Short summary
The TRACMASS trajectory code with corresponding schemes has been improved and become more accurate and user friendly over the years. An outcome of the present study is that we strongly recommend the use of the time-dependent TRACMASS scheme. We would also like to dissuade the use of the more primitive stepwise-stationary scheme, since the velocity fields remain stationary for longer periods, creating abrupt discontinuities in the velocity fields and yielding inaccurate solutions.
