In this directory:
	- Course.odp & Course.pdf: the presentation I did
	- ipythonrc-astro: the "astro" profile file that I created. 
		You will have to copy it in the directory: $HOME/.ipython
		and then call "ipython -pylab -p astro" to start ipython within this "astro" profile.
	- main.py & object3d.py: an example of a main file calling the module object3d 
		where an object definition is done and also a function definition.
	- PracticeX.py: all practice commands shown during the presentation 
		(corresponds to slides: "In practice X:")
	- Practice1.txt: used by Practice1.py command as an input.
	- Practice3.Catalog.fits & Practice3.Map.fits: used by Practice3.py commands.

In the Help directory:
	- Numpy/Scipy/Pyfits/Pylab books or tutorials: .pdf files
	- Arrays.html list all ndarray methods to manage vectors and matrices.
	- Pylab_examples: subdirectoy with python scripts example of plotting functions:
		use them with the command "python example.py"
