getCoefficientMap(label, EigenIdxList)

input value:

1. label: falvor label in std::string format, could be one of B, C, T, Light
2. EigenIdxList is user defined vector containing all eigenvector index that user interested in. output: Map of format map<string, map<string, float>> containing decomposition coefficient of the list of eigenvectors defined by EigenIdxList.

getCoefficients(label, evIdx)

input value:

1. label: falvor label in std::string format, could be one of B, C, T, Light
2. evIdx: The index of eigenvector user interested in. output value: vector of coefficient values. The order is the same as output given by getListOfOriginalNuisanceParameters()

getListOfOriginalNuisanceParameters(label)

input value:

1. label: falvor label in std::string format, could be one of B, C, T, Light output value: List of original nuisance parameter names.

getNumEigenVectors(label)

input value:

1. label: falvor label in std::string format, could be one of B, C, T, Light return value: number of eigen vectors used for chosen label. Return 0 if error occured.
