Two groups of data (HIGH and LOW dispersion) are included in this volume. The
LWP, and SWP data are for comet Shoemaker-Levy 9 and Jupiter. The data
were collected from IUE archive at STScI. 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 (").
An outline of the CD-ROM is shown in the table below:

There are two data forms: resampled images, and spectra (binary). 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.mxlo
or filename.silo (sihi, mxhi). New filenames were converted to end in the
extension "FIT" (FITS became FIT), and for SILO (SIHI, MXLO, MXHI) the first
characters of the old extension were used to replace the second two characters
of the fielname; thus SILO (MXLO, SIHI, MXHI) files could end in "FIT" and
still be unique. For example for SWP (and holds for LWP as well):
SWP12345.SILO -> SSI12345.FIT
SWP12345.MXLO -> SMX12345.FIT
