The very valid question whenever the topic of empirical standards comes up is "Why do you think you need it?" I am unconvinced that empirical standards are ever needed. Of course, I am also unconvinced that I am right in saying that! So who knows...? There is some evidence that empirical stan

Hi Fiona, An experimental standard is a spectrum of a known material (the term is also often used for the known material itself, in addition to its spectrum). If you use Athena to do a linear combination fit, you are most commonly using experimental standards to do it. A theoretical stand
