rspec advice

[graham.hobart]

Hello all, I have collected some first order blazed spectrums from a couple of stars and managed to import the raw files into rSpec, I subtracted background and oreintated it so the first peak can be calibrated as the zero order peak. I then tried to use a reference curve to calibrate the second point- trouble is, in the video on the rspec website they zoom into the curve to highlight salient featrures to match with the reference curve. I am on a laptop and I can't seem to zoom into the curve.
The is Alpha canis majoris (A1 spectral) so I have been using A0ii? I think reference curve.
Any tips on using this programme?

Graham,
can you see any absorption features in the spectrum?

[graham.hobart]

on the first order spectra I can see absorption lines. Not very clear but def there. (it was a tad cloudy) -I would post the file but the raw file is huge and I just converted it to jpeg to reduce size and all the definition was lost.

OK
You should then be able to calibrate the spectrum using the zero order and one of the hydrogen absorption lines...assume the strongest is Hbeta at 4861A.
PM me if you want me to do a calibration to get you started....

So I got to this point and am having a devil of a job getting the subtle lines out of this..
see pm
cheers
Graham.
