WISE All-Sky Release Catalog
================================

The WISE All-Sky Release Source Catalog is available in compressed
(gzip or bzip2) ascii form. Catalog records are lines in a simple
bar-delimited format. Users should be aware that the Catalog table
is extremely large. You will need approximately 280 GB of disk space
to download all of the gzipped files, or 225 GB to download all of
the bzip2-ed files, and an additional 805 GB to uncompress the files. 
Concatenating the files results in a Catalog with 563,921,584 records.

Each Catalog part contains records corresponding to a specified declination
range. If a user desires only the sources within a specified dec range, that
user may choose to download only those Catalog parts corresponding to that
range.  The dec range covered by each file can be found in
http://irsadist.ipac.caltech.edu/wise-allsky/wise-allsky-cat-dec-ranges.txt


================================
Retrieval Instructions:
================================

Use the wget scripts provided for either
gzip (http://irsadist.ipac.caltech.edu/wise-allsky/wget_gz.script) or
bzip2 (http://irsadist.ipac.caltech.edu/wise-allsky/wget_bz2.script) format,
or access via the Web at http://irsadist.ipac.caltech.edu/wise-allsky/index.html

If desired, use the MD5 checksums to verify the download.

Next, decompress all 50 files using bzip2 or gunzip (depending on
format). The files can then be loaded into a database, the details of
which depend on the user's software.

Users may also choose to download only those Catalog parts corresponding to
desired dec ranges.
