The composite spin observable ${\tau }_{22}$≡($T_{22}$+$T_{20}$/ √6 ) has been measured at five incident pion energies between 134 and 294 MeV, in an angular range between 90° and 170°, using a tensor-polarized deuterium target. New, accurate data for the vector analyzing power ${\mathrm{iT}}_{11}$ were obtained at the same time. In combination with the results reported in part I of this series, our measurements allow us to determine the three analyzing powers $T_{20}$, $T_{21}$, and $T_{22}$, separately, and compare them with existing theoretical calculations, all of which fail, in one way or another, to reproduce the entire data set.
