  16. Summary • Sti has more globals & primaries in total. But Stv has more good globals & primaries. (nHits>15). What does it mean?; • Stv has better or equal accuracy almost everywhere ; • Stv has more hits on tracks, especially with big λ or small Pt, which was expected; • Sti has slightly better accuracy improvement when primary vertex included. Probably it is related to refitting with primary vertex which is not used in Stv yet. • Sti & Stv have the same accuracy in energy loss. That means, in spite of very poor Sti geometry description, Yuri succeeded to define it very well. • Stv is not yet tested for Svt, Ssd, Ftpc etc… But Stv must work for Ftpc and other non TPC like detectors. • In both cases (Stv & Sti) hit errors are not good. In result pulls are big (Stv around 5 and for Sti around 3). Fit of errors is needed for both. StarSoft local
