On the time variability of gamma-ray sources: A numerical analysis of variability indices

Diego F. Torres, M. E. Pessah, Gustavo E. Romero

We present a Monte Carlo analysis of the recently introduced variability indices $\tau$ (Tompkins 1999) and $I$ (Zhang et al. 2000 & Torres et al. 2001) for $\gamma$-ray sources. We explor…
