Notes. See Fig. 1b for the definition of the signal regions. Significance values were computed following Li & Ma (1983), assuming a perfect knowledge of the background. ϕ0 and Γ are the best-fit parameter values of the power-law fit for each region (cf. Eq. (1)). 
denotes the square root of the difference in test statistic (TS = −2ln(ℒ)) between the best-fit power-law model and the null hypothesis (corresponding to ϕ0 = 0).
