        1-MINUTE AVERAGED MAGNETIC FIELD WITH SOLAR WIND FLOW SPEED

Title: 1min_ascii_with_sw_speed/
NSSDC ID: SPMS-00705
Old ID: 78-079A-02S
Time span: 78-225 through 79-179 in one-day files


This is an ASCII version of the original binary data set (ID = SPHE-00571; 
old ID = 78-079A-02J), which was never available online. The new ASCII records
are fixed-length, 214 bytes long, with carriage return carriage control. The 
data parameters are the same in the two versions and are in the same order. The
following shows the word structure. The first three items are integers, the 
remainder are real numbers. All items were 4-byte quantities in the original.

This data set covers the time interval 1978 Day 225 (August 13) through 
1979 Day 179 (June 28). Every minute of every day in this time span is represented
in the data, even if there is no valid data for that time. Missing data or bad 
data are indicated by the special value 0.0000E+00 in the V and ISEE position 
fields, and by -1.0E9 in the other data fields. It often happens that there are 
lengthy segments where one or another parameter (or many parameters) are absent, 
as indicated by the special flag values.

The original data were contained on two 9-track tapes, in IBM binary format,
with the following DCB: (LRECL=88,BLKSIZE=26404,RECFM=VBS,DEN=3).

The original tape (ID 78-079A-02J) was created at GSFC by J. King from reduced 
magnetometer data provided by E. Smith (JPL) and plasma data provided by S. Bame / 
R. Zwickl (LANL).

This ASCII version of the data set was created at NSSDC by H. K. Hills in March 
and August, 2002. The conversion from binary was handled by the VAX operating 
system, and a special program unblocked the input and wrote the ASCII output.
The precision of the ASCII version was selected to keep sufficient precision 
without using excessive space.
