Help for old HeliolinC2

Using this, what is the recommended workflow for creating an ITF-to-ITF linkage from OBS80-format observation tracklets obtained from the ITF that are unrelated to Rubin?

I have no idea whether to use make_tracklets.cpp or make_tracklets_MPC80.cpp, or whether to use heliolinc.cpp or heliolinc_new.cpp next, or whether to use link_refine.cpp or link_refine_Herget.cpp after that.
