Initialization: 
---------------
After installation, the program is configured to use "Bright Stars" as star catalogue. 
Additional catalog data are freely available form http://www.astrosurf.org/astropc .
To use other star catalogues you might have installed, it is necessary to launch 
the program and then click on "Catalogues Parameters", enter 45 in "Field Min." for 
" Bright Stars Catalog ". Activate the check box for the new catalogues, 
for example: "Sky2000 ", " Tycho Catalog", " Tycho Input Catalog". 
Check if there is no overlap in the "Min. and Max." field width for the catalogues, 
and indicate 0 for the "Min." of the last catalogue entry. 
If a catalogue is installed in another directory, adjust the field " File " correspondingly. 

You do not have to modify all these parameters immediately after installation, 
because they can be adjusted later according to your requirements. 
See the online help for more details on the initialization procedure. 

In some peculiar network configuration your modem can dial-up when you start ciel.exe, or 
your network is not detected and the "Online resources" function stay grayed. To solve this 
problemes, run "options.exe" and choice "1 Do not control network presence at startup".

Removing the program: 
---------------------
To completely remove this program you have to delete the installation directory and 
all the subdirectories as well as the registry key HKEY_CURRENT_USER\Software\Astro_PC\Ciel. 
Use the program "options.exe" choice "3" to remove this registry key.
