Show affiliationsA 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 information for the reconstruction in the three spatial dimensions is provided by solar rotation and/or multi-spacecraft views. This paper describes, quantitatively, the procedure for implementing DEMT with data from NASA's STEREO/EUVI instrument, including the radiometry, line-of-sight geometry, and image preparation steps. An example of a quantitative, multiband, 3D reconstruction and local differential emission measure curves are given, and it is demonstrated that, when applicable, DEMT is a simple 3D analysis tool that obviates the need for structure-specific modeling.
