Good analysis!

Good analysis Terry!
An extraordinary outcome; 24.1 A/pixel is pretty low resolution even for a SA grating... the distance to the chip could be increased i.e. almost doubled. The severe drop off in the blue-UV is not unusual, but the deep absorption threw me- it just looked to much like a H beta point! Moral of the story? - the info's in the spectra - somewhere!
Looks like Terry's curve has at least been corrected for CCD response and fitted to the Planck curve. ( Tutorial #5)
I've got to ask... Jeff - what was the issue with your first betcar spectra?
Are you doing some pre-processing??
