Hi Jeff,
The .dat files are attached. I must admit I am not 100% happy with the calibration. If it is right then there must be some non linearity as the zero order did not end up very close to zero Angstroms. I used a linear calibration to the two lines which works fine with the small dispersion angles of a 100 line grating but might not work so well with a 300l/mm grating) Also on this basis the response at the red end seems to extend further than I would expect for an unmodded camera (My 350D runs out just beyond H alpha at 6563)
The stronger H Balmer lines of an A star would probably be better to nail the calibration. Vega is well placed here ATM but of course that is no good for you
There's no problem using the stuff on the website in school
Cheers
Robin
