aareadme for /spacecraft_data/explorer/explorer35/ directory.

Explorer 35 (AIMP-2, IMP-E) was launched 19 July 1967
and placed in a lunar orbit where it made measurements of
magnetic fields, plasmas and energetic particles until its end
of life in 1972.  Over the years, NSSDC acquired much data
from Explorer 35 instrument Principal Investigators, although
most of it was on binary magnetic tape.  NSSDC has been
passing a significant portion of these data through its "DIOnAS"
program for writing the mostly binary records into standard
packaging.  Much of the data in this directory are these
DIOnAS'd data sets.  There is presently (July, 2010) no
documentation for these DIOnAS'd data in this ftp directory,
so potential users should contact the NSSDC Request Support
Office at 301-286-6995 if interested in these data.

There are, however, two data sets recently converted (by NSSDC
and the Space Physics Data Facility at GSFC) from original binary
tapes to ASCII files that are also within this directory along with
supporting readme files.  One of these data sets contains 81.92s
magnetic field data from the GSFC magnetometer plus spacecraft
ephemeris data, and the other contains 3-min plasma parameter
data from the MIT Faraday Cup.
