This file describes the installation process for CEDAR.

CEDAR is used for quick look and analysis of COS data.
It is entirely written in IDL and requires at least 
version 5.2 of IDL (uses new IDL data types). It has been
tested on a UNIX (Solaris) and MacOS platform only at this
time.


CEDAR is composed of a number of tools and viewers to look
at COS data in either RAW or FITS format.
It has a built-in database to keep track of images available
according to FITS keyword values.
It comes with on-line help in the form of HTML pages which
can be called from the CEDAR help button.

The following instructions are for people at CASA only.
The software is installed in a common directory.
Copy these files to a directory already defined in your path
(such as ~/bin):

cp ~sbeland/CEDAR/cedar  ~/bin
cp ~sbeland/CEDAR/cedar.def  ~/bin

The first file is the script that will start idl and cedar.
The second file is used to store your personal preferences
for the program (default directories where data can be found
etc.)

Edit both files (cedar and cedar.def) and change path to 
CEDAR_DEF_FILE to point to the new location. 
Nothing else in the file "cedar" should need to be changed.

Edit the file cedar.def and change the default environment 
variables to point to your favorite directories.
The following should not change:
CEDAR_PATH
CEDAR_HELP_PATH
CEDAR_DB_NAME
CEDAR_DB_PATH
ZDBASE

Make the file "cedar" executable:
chmod +x ~/bin/cedar

You should now be able to start CEDAR from the UNIX 
command line from any directory by typing:

cedar
