* Indicates PHA conditions
[If a counting rate has more than one particle specified, the
rate includes contribution from all particle species in the list.]

*  The 6-hour averages were originally provided by the PI team
in 6-month files having no end of record marks after each
6-hour record. These files were originally in this directory.
These files were ingested by NSSDC's DIOnAS process to produce
the 6-month files.

*  These latter files have been verified by Nand Lal to have the same data
values as the input data, and they have end-or-record markers, but the
end-of-record markers are not uniform.  A yet later version of the data
set having annual files and uniform end-of-record markers (i.e., LF) was
created in 2008.  These files have replaced the original PI-provided
6-month files originally in this directory.

*  Hour averages of the interplanetary solar wind data from, and hourly
heliocentric coordinates of, Pioneer 10/11 and other interplanetary
spacecraft may be also be accessed and plotted on-line through the
COHOWeb service.
