WP3 Catalogue

This catalogue builds on the HI identified CME catalogue produced under WP2. Where possible, time elongation tracks are extracted for each CME along a defined position angle corresponding approximately to the apex of the CME. Single spacecraft geometric fitting techniques (see Davies et al., 2012; doi:10.1088/0004-637X/777/2/167) are used to determine the kinemtatic properties (direction, speed and launch time) for three different simple assumptions of the CME morphology. The result is a super-set of the WP2 catalogue containing both the observed parmeters and the derived kinematics. Please read the release notes for the catalogue for further information and caveats related to this catalogue.

This is version: 03 of the catalogue, released 2015-12-09 (minor update 2016-07-01). (DOI: *** still in draft ***)
The catalogue is based on version 3 of the WP2 catalog (DOI: *** still in draft ***) and covers the period from April 2007 to September 2014 after which the spacecraft were moving towards superior conjunction.

The catlogue can be downloaded in several formats (Fixed format ASCII, JSON, VoTable XML).

The time-elongation profiles used for the fitting for all events can be downloaded as a .tar.gz file (HCME_WP3_V03_TE_PROFILES.tar.gz)

catalogue contains the following columns (by default only a subset are shown above but all will be included when you copy or download the data. Use the Show/hide columns option to display the required selection. Events with quality classification of "poor" are not shown):

ColumnDescription
IDThe unique identifer for the observed CME.
Date [UTC] The date and time of the first observation of the CME in HI1 camera.
SCThe observing STEREO spacecraft, (A=Ahead or B=Behind).
L-N Indicator that CME extends beyond the northern edge of the field-of-view (< for sc A, > sc B, blank if edge within FOV).
PA-N [deg] The most northern position angle of the CME span.
L-S Indicator that CME extends beyond the southern edge of the feld-of-view (> for sc A, < for sc B, blank if edge within FOV).
PA-S [deg] The most southern position angle of the CME span.
Quality

A measure of "good", "fair" or "poor", that indicates the quality of the CME observation and confidence that the eruption is by definition a CME. It is recommended that Poor events are not used for CME based studies.
