As a rough guide to what setups work I developed a simple calculator which is hosted on the Rspec website. (The Rspec software there is good for beginners using the Star analyser but you will outgrow it as you progress to more research based spectroscopy)

There is a tutorial on the Star Analyser on the site here

and if you are interested in its development, I talk about it here
