Fig. 3.
Distribution of the pointing directions on the sky in Galactic coordinates in a one-year simulation by CNES (Jaubert et al. 2017). Top: nominal phase. Bottom: extended phase. Filled circles show pointings inside the B1 law, empty circles show pointings outside the B1 law. Green is used to signify general program pointings, blue shows nominal targets of opportunity (transient follow-up, GRB revisits), orange shows exceptional targets of opportunity (exceptional astronomical events requiring fast follow-up), and red signifies GRB follow-up pointings.
