CORIMP CME Catalog

Guide to using the catalog


The CORIMP catalog presents the results of the CME detections in a row/column format, as shown in the image below. The default catalog displays the kinematics derived using a Savitzky-Golay filter on the height-time data (see Byrne et al. 2013). The top links provide access to the kinematics derived from either quadratic fits or linear fits to the height-time profiles.



The columns are divided as follows:

Date
[yy/mm/dd]:
The date of first detection of the CME.
Time
[UT]:
The time of first detection of the CME.
Central PA
[deg]:
The central position angle of the detected CME, measured counter-clockwise from solar north.
Angular Width
[deg]:
The angular width (and upper limit) of the detected CME.
Median Speed
[km/s]:
The median of all 'upper quartile' values in the derived distribution of CME speed.
Max Speed
[km/s]:
The value that is two median-absolute-deviations above the median of all 'upper fence' values in the derived distribution of CME speed.
Median Accel.
[m/s2]:
The median of all 'upper quartile' values in the derived distribution of CME acceleration.
Max Accel.
[m/s2]:
The value that is two median-absolute-deviations above the median of all 'upper fence' values in the derived distribution of CME acceleration.
Min Accel.
[m/s2]:
The value that is two median-absolute-deviations below the median of all 'lower fence' values in the derived distribution of CME acceleration.
Mass
[g]:
The derived mass of the detected CME, at each corresponding position angle and totaled across its angular span.

The rows corresponding to each event are color-coded as follows:

 Red events have a substantial number of detections that span greater than 90°.
 Orange events have a substantial number of detections that span between 60° and 90°.
 Yellow events have a substantial number of detections that span between 30° and 60°.
 White events do not have a substantial number of detections, regardless of their angular span.
 Light-gray events do not have a substantial number of detections, and span less than 30°.
 Dark-gray events are the weakest detections, with potentially untrustworthy kinematics.
