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 |

This CME analysis used STEREO A COR2 science data to measure the plane-of-sky speed. Using the visible source signature in SDO and possible CME fits in SWPC_CAT, a longitude was approximated and triangulation yielded the above 3D parameters. This measurement accounts for a more southward latitude based on the source signature. |

Rough measurement only using early C2 images. Lat/long picked based on early difference images as being fairly center-disk, but the filament eruption was wide and later, more diffuse frames compared to the SDO images of the eruption suggest that most of the material flowed in a more western direction. |

The CME was remeasured after C2/C3 images became available, and it was clear that the CME has a partial halo component (originally only difference images were available). CME was not clearly visible in the difference images, so STEREO_CAT was used. |
