FN_HEAT

FN_HEAT = <Quantity 0.00026805 erg / (s cm3)>

Volumetric heating rate normalization for MAS.

\(Q_0 = P_0 / T_0\) in erg cm⁻³ s⁻¹. Code-unit heating rate 1 corresponds to the reference dynamic pressure dissipated over one characteristic time. This sets the scale for empirical coronal heating prescriptions and wave-turbulence heating in MAS.
