   This file describes the known errors and anomalies for the Neutral

   No NPI data were taken from August 23, 2004 thru October 4, 2004.          
Thus, there is no data release for September, 2004.                           
                                                                              
   The NPI data in July, 2005 covers only a few minutes and all data          
values returned are zeros.  This data is not scientifically useful,           
thus, there is no data release for July, 2005.

   These documents add to the understanding of the ASPERA-3 experiment,       
but are considered non-critical for understanding the contents and usage      
of the ASPERA-3 archived data sets.  All critical information for             
understanding the contents and usage of the ASPERA-3 archived data sets       
are included in the Catalog files, data labels, or some other ASCII form.
