G'Day Jeff,
I had a little play in VSpec myself, and overlaid the Ne lines. I recalibrated it and bumped up the reference Ne spectrum to see the less intense lines. At first I thought there may have been other lines like Ar or He, but I don;t think so... just Ne
.
There's some interesting variation in line strengths. The line Ken mentioned it strong in my reference files, but there seems little correlation (in intensity) to quite a few. Interesting (but I have
no idea what it means
).
