Crowded-field Image Simulator for WSO-UV/ISSIS [v1.0]

This software explores the spatial resolution of ISSIS. For a given combination of UV channel, filters and exposure time, the user creates a set of point-like and extended sources (source model). This source model produces a final image, which takes into account a realistic conversion between physical flux and counts/s, the convolution with the expected PSF, a sky background and noise fluctuations. See the user's guide for details
