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 LE true Plane-of-sky NONE 30.0 675.0 C 12.0 2025-05-11T20:18Z The CME is only seen in SOHO LASCO and GOES CCOR-1 coronagraphs and not seen in STEREO A COR2 imagery. There is an indication that the source is very far-sided. Only plane-of-sky analysis is possible. Not modeled Anna Chulaki on 2025-05-11T17:54Z
