The MFI team created definitive data at 3-sec, 1-min, and 1-hour resolutions
These were provided to NSSDC/SPDF in daily CDF-formatted files with the 
various time resolutions interspersed.  These data were made accessible 
from CDAWeb - http://cdaweb.gsfc.nasa.gov/.

Owing to the likely broad interest in these data, SPDF created ASCII
files, separated by the four time resolutions.

The parameters picked up from the originally submitted CDF files
for the 1-min ASCII files are: 

year,month,day,hour,minute,second
bxgse,bygse,bzgse,bygsm,bzgsm,btotal
bxgsmrms,bygsmrms,bzgsmrms,btotalrms
number-of-points
pxgse,pygse,pzgse,pygsm,pzgsm  (p = s/c position)

The parameters in the 3-sec ASCII files are the same except the spacecraft 
position data are not included.  
The parameters in the 1-hour ASCII files 
are the same except there is no word for "seconds."

The parameters in the 15-sec ASCII files are at 00readme under /15sec_ascii
