Introduction ============ Project AOSSS was started to support telescope+spectrograph simulations carried out at the `WebSim-COMPASS `_ plaftorm. It provides tools to: - create input data cubes for that plataform - download, visualize, generate reports, and organize results from the simulator In addition, there is a tool to plot spectral lines of interest *versus* spectrograph modes coverage at given redshifts. The package also contains a library (API - application programming interface) to deal with photometric problems and to calculate the color of a spectrum. This API is used in the project applications, but may be used more broadly.
