That’s a great investigation Bill. Fascinating to see the orbit of the meteor to go with the spectrum.
The instrument response correction cannot be easy over a wide field. At high resolution on a star, it is surprisingly straight forward once you’ve done it a few times as it is for a narrow part of the spectrum on a tiny field of view. (Though somehow I’ve managed to get a dodgy response curve tonight, but it is still clear so I can redo it.) It must be quite a challenge for meteor spectroscopy through a wide angle lens across a wide spectral range,
Cheers,
Andy
