Problem: the maximum energy is set to the upper energy of the 3rd bin even if there are other bins that satisfy the requirements. Example (1FHLJ2150.2-1413, analysis for tau>1):

Found minimal energy for the analysis to be 0.409297481642
Found maximal energy for the analysis to be 1.73028782549

Change of strategy: in cases when none of the bins satisfies the conditions (excess>10, TS>2, excess/bg<0.05) the analysis can be skipped.

When none of the bin satisfies the required conditions, the analysis is performed in the whole analysis range.
