AB: We present results from a statistical study of coronal mass ejection (CME) signatures. This study will address the often complex and imprecise identification of CME events in the heliosphere, particularly in terms of ejecta boundaries. CME signatures include: a descending velocity profile, a low in situ temperature, a rotating and elevated magnetic field, bidirectional suprathermal electrons, and enhanced composition parameters. CMEs rarely contain all of these signatures and the boundaries of observed signatures are rarely well aligned. In this paper various CME signatures will be statistically examined, both independently and in combination with one another. We hope to more accurately define periods of CME ejecta and to better understand the relationships between the various signatures.
