Thanks and thanks for the kind offer Jack. I’ve got a pdf copy (from the NIST site) of the Multiplet Tables. These “old” works are invaluable even today!
I generally use a selection from the NIST persistent lines catalogue. This has proved an excellent source of data for meteor stuff. Although I don’t think I’ll ever get to needing 0.0001A resolution on my spectra, but you never know LOL! : – )))
PS. Given I’ve found some other metals I suppose I should change the topic title to “Mostly” iron meteor spectrum… ; – )
