Solar wind parameters organized by electron heat flux. Top six panels: averages of solar wind density (normalized by r−2 to remove radial trends), electron core temperature, flow speed, β||, suprathermal fraction (suprathermal electron density divided by core electron density), and the angle between the local magnetic field and the Sun direction for the first two PSP orbits (heliocentric distances < 0.25 AU), as a function of the normalized heat flux components corresponding to the portions of the electron VDF parallel and antiparallel to the magnetic field. Bottom six panels: same quantities for the fourth and fifth PSP orbits. Diagonal lines mark equal and opposite parallel and antiparallel electron heat flux components. Contours enclose the region of parameter space with an occurrence frequency of more than 10% of the maximum.
