Query: Measurement of polarisation observables in $K^0_s\Sigma^+$
  photoproduction off the proton   The reaction $\gamma \, p \rightarrow K^0_S\,\Sigma^+$ is studied in the
photon energy range from threshold. Linearly polarised photon beams from
coherent bremsstrahlung enabled the first measurement of photon beam
asymmetries in this reaction up to $E_\gamma = 2250$ MeV. In addition, the
recoil hyperon polarisation was determined through the asymmetry in the weak
decay $\Sigma^+ \rightarrow p \pi^0$ up to $E_\gamma = 1650$ MeV. The data are
compared to partial wave analyses, and the possible impact on the
interpretation of a recently observed cusp-like structure near the $K^*$
thresholds is discussed.
