The CIO files are available for downloading in both uncompressed and compressed form.
The uncompressed files are ASCII format
files ranging in size from 100 kilobytes to 5.1 megabytes. Most are between 1 and 2 megabytes.
The following table describes the contents of the uncompressed file directory.
FILE LIST
FILENAME DESCRIPTION
CHANGES5.1 description of changes in version 5.1
FORMATS description of file formats
JOURNALS list of journals searched for database
READTHIS description of downloading and the WinZip utility
UNITS definitions of flux units
*.dat (* = 00-23 Main Catalog (25 files)
or 99)+
names.dat+ sources and positions (ordered alphabetically by name)
psc.dat+ IRAS Point Source Catalog data
refchron.dat+ bibliographic references (chronological)
refauth.dat+ bibliographic references (ordered alphabetically by author)
spectra.dat+ spectral data in the Main Catalog
+ included in compressed "tar" files (see below).
The files JOURNALS , FORMATS
, and UNITS provide supplemental information
which is essential for
complete use of the database. To see what changes were made from edition
5 to edition 5.1 of the Catalog see the file
CHANGES5.1.
The compresssed data files consist of twelve 1-megabyte files named
cio01.tar.Z,
cio02.tar.Z ... cio09.tar.Z, names.tar.Z, psc.tar.Z, and
spec+ref.tar.Z, which have been processed with the UNIX "tar"
and "compress" commands. You can download
the compressed data files to a subdirectory of your choice. When
these files are extracted with tar, a "ciov5.1" subdirectory will be created and the
extracted files written there.
If you are using a PC, the .tar.Z files can be successfully uncompressed
with the WinZip utility, which is available from the
WinZip home page.
More information is available about WinZip, or see
the READTHIS
file in the CIO file directory.
When downloading the CIO data files, one should remember to also download the FORMATS, JOURNALS,
and UNITS files.
IMPORTANT!! The uncompressed
Catalog files take up about 39.6 megabytes of disk space.
