Vector_Patches Data Series

Feature identification software will identify a small number of solar active region patches using a line-of-sight magnetogram and an intensity image. This data series pointers to associated vector magnetic field information for each time step during the SDO mission.

# SERIES INFO

  • DATANAME = Vector_Patches
  • Retention = 0
  • Archive = 0
