Hi Robin

Once again – thanks for a full and detailed response!

I had tried with a MILES star comparison but, as you say, it should really be done with something at high res. Interstingly though, I did get an ‘instrument response’ which looked typical of that shown on CB’s page.

If I were to take spectra some of the ISIS database reference stars, could I go back and make IR’s to retrospectively apply them?
