Electron Detection Efficiency
The electron detection efficiency can be described as the quantitative ability of a particular detector to distinguish the electrons from pions. To calculate the electron detection efficiency, first a clean electron sample (Ns) is chosen with the help of the detector other than the one in question. Then, it is investigated how many of those electrons are detected (Nd) in the detector for which we would like to calculate the electron detection efficiency. The electron detection efficiency can be defined quantitatively as the ratio of Nd to Ns.

Pion Rejection Factor
Pion rejection factor (PRF) can be used as another measurement to study the ability of the detectors to separate pions from the electrons. Similar to the electron detection efficiency but this time a clean pion sample (Ns) is chosen with the help of the other detector that isn't under investigation. Then it was counted how many of those fired the detector that is in question (Nd). PRF can be described as the ratio of Ns to Nd.
