Effect of Hadron Contamination on Dielectron Signal Reconstruction in Heavy Flavor Production Measurements

Figure 2

Electron purity measured by STAR in collisions at [6]. The data are fitted using a Gaussian function (“parametrization 1”). We obtained parametrizations 2 to 4 by changing the width of parametrization 1 by 1, 2, and 3 uncertainties of the width of parametrization 1.
