Wind Magnetic Field Investigation (MFI) Composite Data in RTN Coordinates

Wind MFI composite data in RTN coordinates. The files contain multiple time resolution data: 3-second, 1-minute, and 1-hour. Final Version 5 data are accessible to within about 3 months of current date, newly defined Version 4 data (with final Bz offsets and not-yet-final spacecraft position vectors) between 3 months and about 2 weeks of current date, and newly defined Version 3 data (with the most recently determined Bz offset value, not yet final for the Version 3 interval) from 2 weeks to about 2 days of current.

User will acknowledge the Wind MFI instrument team, and the site from which data are pulled, in any publication resulting from the use of these data.
