Photometric monitoring of Beta Pictoris in 1981 showed anomalous fluctuations of up to 4% over several days, consistent with foreground material transiting the stellar disk. The subsequent discovery of the gas giant planet Beta Pictoris b and the pre

In September 2016, the microquasar Cygnus X-3 underwent a giant radio flare, which was monitored for 6 days with the Medicina Radio Astronomical Station and the Sardinia Radio Telescope. Long observations were performed in order to follow the evoluti

Rules of thumb to increase the software quality through testing

Autor: Sergio Poppi, M. Buttu, Andrea Orlati, Marco Bartolini, Carlo Migoni, Simona Righini

Publikováno v: SPIE Proceedings.

The software maintenance typically requires 40-80% of the overall project costs, and this considerable variability mostly depends on the software internal quality: the more the software is designed and implemented to constantly welcome new changes, t
