Abstract The tracking efficiency and fake rate have been measured using e+e− → τ+τ− events, where one tau lepton decays leptonically (τ → l±ν ν ̄ , l = e, μ) while the other decays hadronically into three charged pions (τ → 3π±ντ + nπ0). These measurements were performed using the e+e− collision data recorded during the 2019a, 2019b and 2019c data taking periods. This document contains the approved plots and captions.
