Re: VV Cep spectroscopy reference star ?

Hi Thilo,
I am currently following VVCep (~3800-4100A). For relative flux calibration I am currently using Altair from the UVES POP "bright stars of the southern sky" and Vega from the CALSPEC list. This gives me measurements at two altitudes so I can calculate extinction more accurately if I need to but I have not bothered to do this yet. CALSPEC is not ideal though as it is at a significantly lower resolution than I am working at.
Cheers
Robin
