Class for the resolution function. It can be built from local file or from db.

| ResolutionFunction::ResolutionFunction | ( | TString | identifier | ) | [inline] |
The constructor takes a string identifying the parameters to read. It parses the txt file containing the parameters, extracts the index of the correction function and saves the corresponding pointer. It then fills the vector of parameters.

| ResolutionFunction::ResolutionFunction | ( | const MuScleFitDBobject * | dbObject | ) | [inline] |
This constructor is used when reading parameters from the db. It receives a pointer to an object of type MuScleFitDBobject containing the parameters and the functions identifiers. The object is the same for all the functions.
