1  Simple relativistic Breit-Wigner fit with model-dependent width.
2  Simple relativistic Breit-Wigner fit with constant width.
3  One peak fit result.
4  Parameters roughly estimated, not from a fit.
5  Skew mass distribution compensated by Ross-Stodolsky factor.
6  Width errors enlarged by us to 4${}\Gamma /\sqrt {\mathit N }$; see the note with the ${{\mathit K}^{*}{(892)}}$ mass.
