Fractions of ν_e, , ν_τ, and chemical potentials of electrons, protons, and neutrons computed in post-processing for (BLh, 1.00) at 4.6 ms after merger. In the upper panels, we show the fraction of ν_e (left), the fraction of (centre), and the fraction of ν_τ (right). In the lower panels, we show the electron chemical potential (rest mass subtracted) μ_e − m_e (left), the proton chemical potential (rest mass subtracted) μ_p − m_p (centre), and the neutron chemical potential (rest mass subtracted) μ_n − m_n (right). We note that the colour bar scales are different for the various chemical potentials. As in Fig. 1, the black lines mark the isodensity contours.
