The SHARK-VIS Simulation Code (SSC) is an IDL-based code based upon the PROPER optical propagation library for the simulation of the instrument perfoemances under different seeing conditions. The main code is composed of the following routins: SHARK_SIMULATION.pro it is the main code param.dat it is the parameter file for the set-up of the simulation pisces_on_axe_mask_2.pro it computes the on-axis (occulted) AO PSF pisces_on_axe_phased.pro it computes the off-axis PSF. Also representative of the observing mode without coronagraph. contacts: for further information on how to run the code and adapt it to other AO high contrast instruments please contact: marco.stangalini (at) inaf.it
