Description
The Cherenkov Telescope Array Observatory (CTAO) represents the next generation of Imaging Atmospheric Cherenkov Telescopes, the most effective ground-based instruments for gamma-ray detection. Compared to the current generation, CTAO introduces a significant leap in capabilities with a large number of telescopes distributed across two sites: 15 in the Northern hemisphere and 60 in the Southern hemisphere. This configuration enhances energy sensitivity, broadens the observable energy range, and improves source localization. The high number of telescopes also provide the unique opportunity of testing new pointing strategies, which are not feasible with the current generation, limited to a maximum of five telescopes. In particular, the benefits of a divergent pointing strategy -consisting of telescopes pointing in a slightly outward direction from one another- has been studied since 2013. This approach expands the field of view (FoV) at the cost of reduction in sensitivity and resolution. Conversely, narrowing the FoV with a convergent mode can improve these aspects, providing flexibility for diverse scientific goals.
