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 SWPC_CAT 25.0 -46.0 534.0 C 25.0 2025-09-26T02:00Z Best fit measurement using source location seen in UV imagery with some southeastward deflection, several frames of SOHO LASCO C2, one frame of SOHO LASCO C3, and one frame of STEREO A COR2. Leading edge becomes too diffuse to track a few frames into the SOHO LASCO C3 field of view. 1: Result 1 (2.0 AU)
