Function Documentation

GetAlphaSuffix()

std::string GetAlphaSuffix

(

float

alpha

)

---

This is a helper function that provides the suffix for NSubjettiness and NSubjettiness ratio decorations. No suffix is used for alpha = 1.0 and other values are given a suffix of _AlphaN where N is the value with decimal points removed. This assumes alpha values of [0.0,9.9]

and that the maximum precision is 0.1.

  // 10*alpha is used in the suffix

    suffix = "_Alpha" + std::to_string(int(alpha*10));
