Likelihood

1. Only calculate the expected likelihood (set Nobserved as Nexpected)

2. Consider some uncertainties such as efficiency, theoretical which use last year result.

3. For 1D using 2000 points for each ATGC parameter; For 2D using 200*200 points for each 2 ATGC parameters.

ATGC parameter limits set

1. For 1D exactly as last year method

2. For 2D cut a plate in 2D likelihood and get the boundaries as 2D parameter limits
