Web15 May 2015 · you may instead of doing hist->GetSumw2 ()->GetSum () do a loop "by hand" hist->GetSumw2 () and to make the total because GetSum () would take as well the underflow and overflow. So GetSum () would not allow to obtain the appropriate error on your total sum of weight. WebIn the Sum-of-non- zero terms method the weights of non-zero binary bits are summed, as the weights of zero binary bits do not contribute towards the final sum representing the decimal equivalent. The weights of binary bits starting from the right most least significant bit is 1, The next significant bit on the left has the weight 2, followed by 4, 8, 16, 32 etc. …
