Quantitative, three-dimensional analysis of the global corona with multi-spacecraft differential emission measure tomography

A previous paper (Frazin et al. 2005b) introduced the concept of differential emission measure tomography (DEMT), which is a three-dimensional (3D) extension of the classical differential emission measure technique for determining the distribution of temperatures in a volume of plasma. The informati...
