Definitive Proof that the Corona is Tens of Thousands of Times More Dense than Earth's Atmosphere

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.
