They should live in /home/data/terascan/bin

This is the required directory structure of /home/data/terascan (and 
/home/data.template.terascan)

They should all be owned by the user sssg.

The file sssg.pgs.tar is (hopefully) a collection of the required scripts on
tera.  These are all TeraPgs scripts that can be installed directly, or used as templates.  Note that the distribution records will need to be changed for a 
ship other than Oceanus.  Noteably, the area of interest, target machine( april
or mike) and user password will need to be changed.

thumb.avhrr3 and thumb.sst will need to be changed to reflect the correct 
shipname.

thumb.cron should be installed as a cron job for user sssg on mike or april:

8,18,28,38,48,58 * * * * source /etc/profile;/home/data/terascan/bin/thumb.cron

Finally, the file /var/www/html/index.shtml should get entries similar to the 
following:

<li> <a href="/data/terascan/sst/index.html">Terascan sst Images</a></br>
<li> <a href="/data/terascan/avhrr3/index.html">Terascan avhrr3 Images</a></br>


Good luck
