Dear Helmut and ElMaestro,

» Eyeballing, of course.

That's how I do it too. I don't trust automatic calculations by whatever software. It depends so much on the parameters you enter. You may get a S/N of 30 with the plot you provided. Nonsense.

» Peak height 13.7 gives S:N ~1.8. Not an awful lot.

With a visual quick and dirty look I would have said 3, but I was too fast and I was wrong (stupidly took the signal from the bottom of the graph). Revised slower-and-still-dirty estimate 2.

Regards
Ohlbe
