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 software was developed in the framework of the SHARK-VIS instrument design, and the first release was in 2013. The results of the code were validated by using on-sky data acquired in 2015 with the SHARK forerunner experiment at LBT. For more information about the code and the instrument please refer to: Stangalini+ 2014; Stangalini+ 2016; Pedichini+ 2017; Mattioli+ 2018; 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
