Simulator for astronomical stellar crowded fields – GlencoeSim

This package creates artificial images of stellar fields including simulations of Point-Spread Functions, spatial stellar distributions and darkframe (noise). Knowledge of original stellar positions and noise statistical distribution is useful for tests of reverse algorithms such as Blind Image Deconvolution, especially in case of stellar globular clusters. Software is implemented in MATLAB code.
