Comparison of magnetic field observations of an average magnetic cloud with a simple force free model: the importance of field compression and expansion

We investigate the ability of the cylindrically symmetric force-free magnetic cloud (MC) fitting model of Lepping et al. (1990) to faithfully reproduce actual magnetic field observations by examining two quantities: (1) a <i>difference angle</i>, called β, i.e., the angle between the...
