Just to add that this was my first time trying to generate TLE sets, so the accuracy isn’t the best. However the latest set, generated from more data by @cgbsat, is based on a better procedure for fitting, again using the strf tool that PE0SAT linked, so it should be much better and accurate than the previous produced.
