Two groups of data (HIGH and LOW dispersion) are included in this volume.     
The data are LWP measurements of 38 comets observed by IUE.  Added            
information is included from the Uniform Low Dispersion Archive Guide No. 2   
(ESA SP1134), such as a General List of comet observations from 1978-1989.    
The data files were collected from IUEMAST.   A FITS to PDS translator (F2P)  
has been used to create the detached PDS labels.    The data were checked     
by manipulating the data with IDL routines created at the Small Bodies Node.  
In the DOCUMENT directory are explanatory text files as well as digitized     
versions (1&2) of the manuals in TEX or ASCII text with figures as JPG        
files. All document files and most labels contain an 80-byte fixed length     
record, with a carriage return (ASCII 13) and line feed (ASCII 10) as the     
79th and 80th byte respectively.   All the tabular files in the INDEX and     
DOCUMENT directory are formatted according to PDS standards.   It should be   
noted that the index tables are formatted so that they may be read directly   
into many database management systems.   All fields are separated by commas,  
and character fields are inclosed in double quotes (").                       
49 comets were observed by the IUE during the period.  Of these, 38 were      
observed using the LWP.  The cpmplete list of comets is shown below,          
with the LWP comets marked by an asterisk (*):

Three forms of data may be included.  The extracted spectra as binary tables  
(INES), resampled images (SILO, SIHI), and raw spectra (MXLO, MXHI). After    
data reached the Small Bodies Node, some file names were changed to meet ISO  
standards. The original files came in FITS format in the form filename.ines   
or filename.silo (sihi, mxlo, mxhi).   As the new filenames had to end in the 
extension "FIT" then FITS became FIT, or for SILO (SIHI, MXLO, MXHI) the first
characters of the old extension were used to replace the second two characters
of the file name; thus SILO (MXLO, SIHI, MXHI) files could end in "FIT" and   
still be unique.  For example:                                                
       SWP12345.SILO   ->       SSI12345.FIT                                  
       SWP12345.MXLO   ->       SMX12345.FIT                                  
The same holds true for LWP and LWR data.
