The Software for Modeling FETCH Observations of 2005 May 13 CME

The following MATLAB codes and inputs were used to create the majority of figures and tables in the **submitted** ApJ article (#AAS55701), "Modeling FETCH Observations of 2005 May 13 CME". 

Abstract

Coronal Mass Ejections (CMEs) evolve significantly as they propagate from the Sun to the Earth, so remote observations of changes in speed, strength of the magnetic field, density, and overall structure are critical for predicting their arrival time and geoeffectiveness. Radio remote observations of Faraday rotation and Total Electron Content combined with white-light observations enables the measurement of these properties with careful analyses. This paper describes the analysis techniques and evaluates their accuracy with regard to measuring a CME’s complex evolving structure and speed. The approach utilizes the layout of the Faraday effect tracker of coronal and heliospheric strutures (FETCH) with AWSoM simulations as input for evaluating these radio-based measures.
