Figure 9

The upper panel shows the distribution of TPC track $\chi^2$ residuals from offline track reconstruction obtained using total cluster charges from offline cluster finder (Offline CF) and different versions of the HLT hardware cluster finder (HWCF) Tracks, reconstructed using the TPC and ITS points, satisfy the following selection criteria: pseudorapidity $|\eta| < 0.8$ and $N_{\text{TPC clusters}} \geq 70$ The ratios of the distributions obtained using the offline cluster finder and the HLT cluster finder are shown in the lower panel.
