A simultaneous fit of b$\overline{b}$, c$\overline{c}$, s$\overline{s}$ (bcs pairs) and c$\overline{s}$ spectra
A previous fit of the J/ psi and Upsilon levels and leptonic widths by a power-like phenomenological potential is modified to include systems containing strange quarks. In spite of the smallness of the strange quark mass, the fit is astonishingly good. (16 refs).
