EEGGL is a tool which uses observational data to specify input parameters for the Gibson-Low flux rope model so that it may approximately reproduce observed CME events. EEGGL allows the user to specify the CME source region with the use of synoptic magnetogram data, which in turn provides the location and orientation of the GL flux rope. The observed CME speed provided by StereoCAT is used to specify the magnetic field strength of the flux rope.
