The List of CME Analysis already entered:
Event Type Catalog
Measurement TypeCME measurement type: Leading Edge (LE), Shock Front (SH), Right Hand Boundary (RHB), Left Hand Boundary (LHB), Black/White Boundary (BW), Prominence Core (COR), Disconnection Front (DIS), Trailing Edge (TE).
Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type. This is a helpful flag if you would like to download only one most accurate CME analysis per CME per Measurement Type

CME Analysis M2M_CATALOG true 130.0 5.0 2800.0 R 65.0 2012-07-23T04:10Z This is a combination of Leila's measurements with measurements by Temmer et al. (2015), and Liu et al (2014). For an ENLIL simulation in Bain et al (2015, submitted), this was used together with parameters dcld=8, and xcld=4. Not modeled Leila Mays on 2015-10-23T15:05Z

CME Analysis M2M_CATALOG false 125.0 2.0 2500.0 R 70.0 2012-07-23T03:50Z Triangulation using C2/C3, COR2B with scc_measure by Leila (see Baker et al, 2013, doi:10.1002/swe.20097). With error bars: "The CME was determined to have a three-dimensional speed of 2500 ± 500 km/s in the direction of 125°+15°/-5° longitude and 2° ± 10° latitude (in HEEQ coordinates), and a full angular width of 140° ± 30°."

CME Analysis M2M_CATALOG false 124.0 NONE 2600.0 R 0.0 2012-07-23T03:45Z Triangulation measurements by Liu et al. (see http://dx.doi.org/10.1038/ncomms4481) using COR1B, COR2B, C2 C3. Parameters are taken from Figure 4 at a height of 21.5Rs. Latitude and width are not given. " The speed of the CME leading edge first increased to about 3,050 km/s around 03:14 UT at a distance of about 13 solar radii and then decreased to about 2,700 km/s."

CME Analysis M2M_CATALOG false 130.0 5.0 2270.0 R 65.0 2012-07-23T04:14Z This is the CME magnetic structure measurement by Temmer and Nitta (2015), Solar Physics 10.1007/s11207-014-0642-3. With error bars: CME Magnetic Structure: v_max=2270±420 km/s, lon=130°±5°, lat=5°±5°, face-on half-width=130°±5°, edge-on half-width 60°±5°, tilt=60°±5° CME shock v_max= 2580±280 km/s CME mass from COR2B ~1.5±0.5x10^16 g.
