Total cross sections, angular distributions, and decay asymmetries have been measured for the reaction ${\pi }^{-}p\to {\Sigma }^{-}{K}^{+}$ at pion beam momenta of 1.12, 1.23, 1.27, and 1.32 BeV/c. Legendre-polynomial expansion coefficients for the angular distributions are presented and compared with other data. Preliminary results of a partial-wave analysis are discussed.
