STEREO/PLASTIC determines three-dimensional distributions of solar wind iron ions with unprecedented time resolution.Typically 300 to 1000 counts are registered within each 5 min time interval.For the present study we use 5 Piece Twin Sleigh Bedroom the information contained in these distributions to characterize CIRs (Corotating Interaction Regions) in two test cases.We perform a consistency test for both the derived physical parameters and for the analytical model of CIRs of Lee (2000).At 1 AU we find that apart from compositional changes the most indicative parameter for marking the time when Rain Jacket a CIR passes a spacecraft is the angular deflection of the flow vector of particles.

Changes in particle densities and the changes in magnitudes of speeds are apparently less reliable indicators of stream interfaces.
