Heating model
 Heating model 1: Empirical coronal heating model described in Lionello et al 2009. This model has three components tailored for the fast wind/coronal holes, the quiet sun, and active region. Volumetric heating depends only on local parameters of the 3D magnetic field. Heating model 2: Empirical coronal heating model used for recent eclipse simulations conducted by Predictive Science, Inc. Like the Heating Model Version 1.0, this model features multiple components designed to match the multi-spectral emission of the corona, but in this case volumetric heating depends on surface magnetic field properties as well.
