Notes. Columns: (1) source name. (2) Observation epoch. (3) Energy threshold. (4) Observed integral flux above energy threshold. (5) Probability for a fit of the flux with a constant.

(a)

The constant-flux hypothesis (daily timescale) is rejected at a 3σ confidence level if the fit probability is less than 0.27%.
