+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
