measured in the TPC for the transverse-momentum ranges $2\ \leq p_{\mathrm{T}} < 3\ \mathrm{GeV}/\textit{c}$ (left) and $3\  \leq p_{\mathrm{T}} < 4\ \mathrm{GeV}/\textit{c}$ (right). The vertical bars represent the statistical uncertainties of the data. The blue and the red dash-dotted lines indicate the $^{3}$H and $^{3}$He contributions, respectively, while the black solid lines are the total fits. The ranges used for the signal extraction are indicated by the vertical red-dotted black lines.
