Hi, is anyone able to provide current high res data with: - R > 25.000 - SNR 150 or better - from 6330 to 6450 Angstrom, on a star (Rho Cas) with about mag 4.7 and Teff about 7300 Kelvin? We have a problem with emission in absorbtion lines and want to test an idea! Please contact us in this thread or via pm. Cheers Malin and Christoph |

Hi Daniel, thank you! We know already this data. The problem is, that we need current high res data on Rho Cas. That means not older than three weeks. Cheers Christoph |

Hi Malin and Christoph, Enclosed a 2400 s rhoCas spectrum from last night with R 22600 and SNR aprox. 150. Currently the system works with 2 x 2 binning close to the Nyquist sampling. Better resolution could be possible with smaller entrance slit and 1 x 1 binning but would kill the SNR…. Other orders of Echelle spectrum are also available. Kind regards, Ulrich
