Hi Derek,

Hi Derek,

Thanks, Having tried film based spectroscopy for some 15 years I know the difficulties. I never captured a single one!

I was glad to help, it has been an interesting challenge. It always feels good when you finally see it come together and you actually understand what you’re looking at!

Great fun,



PS. Will you be attending the BAA weekend in September at Armagh, or perhaps the IMC again, in Germany this year. Looking forward to catching up with you at some point.
