The datasets support the figures in the paper <em>Refining pulsar radio emission due to streaming instabilities: Linear theory and PIC simulations </em>(figures \(2\) to \(7\)) and provide additional information discussed in Section \(5\) of the paper. They contain parametric studies investigating a relativistic dispersion relation for an electron-positron pair plasma near a pulsar. The investigated quantities are the maximum growth rates (max_growth_rate) in units of \(10^{-3}\omega_\mathrm{p}\), an integrated value over the entire range of positive wave growth (int_growth_rate) in units of \(10^{-3}\omega_\mathrm{p}\), the fractional bandwidth (bandwidth) in units of \(\omega_\mathrm{p}\), the minimum and maximum values where the growth rate exceeds a threshold value of \(2.8\times10^{-4}/\omega_\mathrm{p}\) - which can be associated to effective wave growth - in units of \(1 / d_\mathrm{e}\) (k_thr_min and k_thr_max) as well as a relative deviation of the range between these two values and the entire range of positive wave growth (rel_dev). All of these parameters are investigated while changing a specific parameter in the dispersion relation (\(\rho_0\), \(\rho_1\), simultaneously \(\rho_0\) and \(\rho_1\), \(\epsilon_\mathrm{n}\) and \(\gamma_\mathrm{b}\), the latter once with \(\epsilon_\mathrm{n}=10^{-3}\) and once with fixed \(n_0 = n_1 =1\)and variable \(\epsilon_\mathrm{n}=10^{-3}\)). These parameters appear in the titles of the text files which contain the respective dataset.
