 # Functions and their parameters:
 
+### TMefficiencyClass::TMefficiencyClass()
+Constructor of the TMefficiencyClass. Based on the varName input parameter, it sets the 
+
+* **Parameters**
+    * string varName
+
+### void TMefficiencyClass::fillBinEdges()
+Takes the TM efficiency class nad based on the number of bins and the overall bin range fills `binEdgesEquidistant`
+
+### void TMefficiencyClass::isEq()
+Checks whether the varName parameter contains string "\_equal" if yes, sets `isEquidistant` to true and remove the "\_equal" from the varName.
+* **Parameters**
+    * string &varName
+    
+### bool TMefficiencyClass::check_vector_size()
+Checks whether the size of the binEdges (or binEdgesEqudistant if isEquidistant is true) array is equal to nBins+1.
+* **Parameters**
+    * bool isEqui
+* **Return**
+    * True if everything is okay, False if the bin-edge array size is not equal to nBins+1.

 ### bool useExtraVarBool()
 This functions checks whether the used extra variable is listed in the binning scheme defined in the TMefficiencyClass. **ṪODO** add a link
