Solar wind parameters measured on the first (left column) and second (right column) PSP orbits. The panels show the angle between the magnetic field and the Sun direction, the solar wind speed (from SPC), electron pitch angle distributions at 314 eV, the ratio between the parallel electron thermal pressure and the magnetic field pressure β_||, the electron heat flux, and the electron heat flux normalized by the saturation heat flux. The net heat flux is shown in green, together with components corresponding to the portions of the electron VDF parallel (Q+, blue) and antiparallel (Q–, red) tothe magnetic field. Diamonds on the time axes indicate perihelion on each orbit.
