VV Cep and some Be stars with DADOS-1200
Posted: Mon Jun 19, 2017 6:55 pm
Hello,
here are some spectra of Be stars (already at the BeSS database, except VV Cep) taken with the DADOS and the 1200 l/mm. This night the spectrograph performed particularly well. The resolution from night to night is quite variable (why?) but this night it reached R=7000. It depends of focusing, I believe. A very small variation, and the resolution can reach 7000 or be lower than 5000.
Greetings
Fran
