The accepted solar physics is that the density of the Sun's corona is
only 1/10,000ths of Earth's atmosphere. Robitaille disproves this by
relying on Zirin's refutation of Saha's equation in the following way.
Ionization in the corona would be maximized either by a minimum pressure
or a maximum temperature. Saha's equation relied on a low-temperature
estimate from the ionization, giving the corona low pressure. However,
the ions Iron 14 and Iron 13 are of equal abundance, there so from the
Elwert ionization theory, this provides a temperature of one million
degrees such that the pressure must be at least tens of thousands times
more than Earth's atmosphere.

If the pressure in the corona were tens of times more

the corona would also radiate black body radiation. At temperature
1 million K, the radiated energy would be 0.9e9 (0.9 billion) times
what it is.

That's why we know that the pressure must be _much_ less
than in the photosphere.

That's why we can see the photosphere through the corona.

The corona emits no blackbody radiation, and a denser corona would not
emit blackbody radiation either. It would block more of the blackbody
radiation from the photosphere concealing the higher temperature there
than the 5778K believed in.
