Errata to Version 01 & 02 of SWOOPS Ion User's Guide
------------------------------------------------------------------------------

02/03/95: All document and data files with date versions through this date are
either those orginally supplied by the SWOOPS team or more recently updated as
of this date. Files affected by revisions included the hourly data file and
the high resolution data file for 93/274 - 93/365; only the files dated 2/3/95
or later for these data should be used.

06/18/95: As of this date the SWOOPS ion data, including high resolution and
hourly average data files, were completely updated from launch through first
quarter 1994 after reprocessing by the P.I. team. SWOOPS ion data files created
earlier than this date should be discarded. Version 01 of the user's guide is
still in effect.

12/16/96, message from Bruce Goldstein, JPL: 
The SWOOPS ion documentation for data submitted to the NSSDC has been
updated to correct an error and to warn users about differences between
the data used for hourly averages and high resolution temperature estimates.
(The documentation said that there were more combined mode spectra than
O/E mode spectra, this is the reverse of reality; it would not have any
effect on anything a user did but was provided to explain why we did
some averaging in a certain fashion). There is also a warning added
that since the hourly averages of temperatures are based upon combined
data they will be somewhat lower than an average that a user might compute
himself based on the O/E mode data.

These are just informational points and do not represent any sort of errata
or correction to the data. The new document file at NSSDC is named 
SWOOPS_ION_USERS_GUIDE_V02.DOC. No changes have been made to the data files
in the NSSDC data set.
