For the events, which do not lie close to the limb, we will gather the necessary coronal plasma parameters from the synoptic MHD model1 of Predictive Sciences, Inc. (PSI). Their MHD Around a Sphere (MAS) model has been extensively validated2, and its results are freely available for download (in Hierarchical Data Format), for both the coronal and heliospheric domains3. Figure 1F shows as an example an equatorial cut of radial velocity out to 30 Rʘ, for a particular Carrington rotation. Similar 3D maps of heliospheric plasma model properties are also readily available, extending beyond 2 AU. We will develop an interface for reading and interpolating the coronal PSI maps in Work Package 2. An interface for the heliospheric maps is already available in EPREM.
