I took this on 09-03-13.
Used iota Del for instrument response.
Processed in ISIS. Not sure if it is correct.
Please comment.

Hi John,

The features are there but your instrument response correction may not have worked correctly. If you compare your spectrum with Christian's on the same night from the database
http://www.astrosurf.com/aras/Aras_Data ... _cbuil.fit
you will see that Christian's continuum is much flatter compared with yours. The result for example is that your H beta line appears larger than H alpha

One first simple check you could try is to apply your instrument response it to your uncorrected spectrum of iota Del. It should then be almost identical to the iota Del spectrum from the MILES database.


Cheers
Robin

Thanks Robin,

I will check both of those right now.
