The results of analysis of these measurements have been reported in St.Cyr et al, 1997, Proceedings of the 31st ESLAB Symposium, held at ESTEC in Noordwijk, Netherlands during September 1997. Date = date the CME first appeared in C2 First Time [UT] = the UT that the observer believed the CME first appeared in C2 Central PA = Position Angle of central axis of CME Width Altitude = the height (measured from Sun-center) at which the Width was measured Width = the angular span of the CME Primary Speed = measurement of the earliest identifiable feature in the mass ejection H-T Fit = order of polynomial used to fit the height-time curve for speed (1st order = constant velocity; 2nd order = constant acceleration) Speed Feature = the morphology of the feature measured (LE=Leading Edge) Concave-Out Feature = Was this morphology detected during the late stages of the CME?
