However, very few people might have the patience to download,
compile and install the software on their local machines.
Many people may prefer to have a quick look at the simulated
sky than to study the details — a first look at what the instrument
would see. That was the main motivation behind the web interface
ASTUS. We hope this tool will be useful for everyone, starting from
casual web surfers to busy astronomers. One may download the
simulated data as images of individual fields, or just check count
levels on screen.
