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 -85.0 25.0 1104.0 O 19.0 2025-08-28T23:30Z Best fit measurement using several frames of GOES CCOR-1 and a few frames of STEREO A COR2. The leading edge is extremely diffuse, adding some uncertainty to this measurement. This CME was captured by only one frame of SOHO LASCO C2 in real time, due to a regularly scheduled downlink data gap which began 2025-08-28T20:24Z. 1: Result 1 (2.0 AU)
2: Result 2 (5.5 AU)
