The research team was doing to as a technical proof of concept using readily-available letters. They didn’t especially care about Marie Antoinette.

The Ars article is terrible at conveying this; you have to get to the 7th paragraph to get even the first hints of this. I usually expect better from them.

I agree. I was trying to find out what synchrotron they used, Ars doesnt say! Went to read the paper, apparently they used some portable device for the xrf instead.
