MFI SWE Ephemeris

Output Option:Create ASCII File Plot

Date:   The date may be entered in either Day of Year (YYYYDOY) or Year Month Day (YYYYMMDD) format

Start Date:        Start Time: (HHMMSS)  
  End Date:         End Time: (HHMMSS)  

Coordinate System: GSE GSM

MFI Time Resolution: 3 second 1 minute 1 hour
These resolution choices apply if MFI parameters (the first 6 parameters) are plotted only.
If plasma parameters are plotted then MFI data is averaged to match the 92 second resolution of the Solar Wind Experiment (SWE) instrument.
