title: Optimal defocus distance for testing the 2.1 m telescope at San Pedro Mártir.
abstract: Within the preliminary development of a low-cost active optics system (AOS), computer simulations have been performed. The general purpose of simulations is to find an optimal scheme for the wavefront control of the primary mirror. We present results for the wavefront sensor of the AOS proposed for the 2.1 m telescope at San Pedro Mártir. The method presented here can be used for any other telescopes as well.
