Quality cuts optimization for detection (srcind)

Since the AllSky MC is a tailored production than the Fixed MC production, we cannot use high-zenith Crab observations to find the best cuts for detection. To do so, I found the best cuts (gammaness and theta) that minimise the sensitivity of MC gammas re-weightening the slope the the spectrum reported by MAGIC (Gamma = -3.7) and using OFF data from real OFF data (3 reflected OFF regions from runs 5890,5891,5892,5893, 5912,5913,5914,5915,5916,5917, 5942, 5943, 5944, 5945, 5970, 5971, 5972, 5973). I used a grid of gammaness and theta2 values. The best cuts are gammaness = 0.9 and theta2 = 0.01 deg2.
