Let's fix it to be compatible with PTC. A cross-check with the SAD manual could confirm or not the problem...
Reviewing the SAD manual, it seems that compared to entry and exit, a
is flipped sign, but b
is not. So it looks like we are correct.
See https://www-kekb.kek.jp/Documentation/SAD/?Elements/QUAD#q=fringe for more detail
Performing an ng vs ng test reveals that for the map to be fully reversed when chg is reversed, f2 must also be multiplied
HOWEVER I am not sure if f2 should also be multiplied by lw. It is not in PTC (but it's also not multiplied by charge), so this needs to be reviewed.
