Query: Coronal temperature profiles obtained from kinetic models and from
  coronal brightness measurements obtained during solar eclipses   Coronal density, temperature and heat flux distributions for the equatorial
and polar corona have been deduced by Lemaire [2012] from Saito's model of
averaged coronal white light (WL) brightness and polarization observations.
They are compared with those determined from a kinetic collisionless/exospheric
model of the solar corona. This comparison indicates rather similar
distributions at large radial distances (> 7 Rs) in the collisionless region.
However, rather important differences are found close to the Sun in the
acceleration region of the solar wind. The exospheric heat flux is directed
away from the Sun, while that inferred from all WL coronal observations is in
the opposite direction, i.e., conducting heat from the inner corona toward the
chromosphere. This could indicate that the source of coronal heating rate
extends up into the inner corona where it maximizes at r > 1.5 Rs well above
the transition region.
