Performance of the SST-1M telescope of the Cherenkov Telescope Array observatory

The single mirror small-size telescope(SST-1M) is one of the telescopeprojects being proposed for the Cherenkov Telescope Arrayobservatory by a sub-consortium of Polish and Swiss institutions. The SST-1M prototype structure is currently being constructed at the Institute of Nuclear Physicsin Cracow, Poland, while the camera will be assembled at the University of Geneva, Switzerland. This prototype enables measurements of parameters having a decisive influence on the telescopeperformance. We present results of numerical simulations of the SST-1M performance based on such measurements. The telescope effectivearea, the expected trigger rates and the optical point spread functionare calculated.
