Abstract:

CONCLUSION Simulations are an important tool in support of HI observations For complex events CME-CME interaction What happened Testing different physical mechanisms To test and validate methods Simulations are like a controlled laboratory environment CME speed and direction are known, Can vary only one parameter. We tested the Fixed-Phi and Point-P approximations. We devised a new approximation which fits better our simulated CME and is important at large elongation angles beyond 40-deg. Lack of fastwide CMEs may explain why fitting method work so well so far.
