A high signal to noise spectrum of Beta Cen with CRIRES

Smoker, Jonathan

"A near-infrared spectrum between 1483.0 and 1516.3-nm at a spectral resolution of 50,000 is presented using CRIRES. The target chosen was Beta Cen with mH=1.209 mag and observations were taken using natural seeing (NoAO). With a one-hour observation we obtained 30 spectra which were reduced using the ESO CRIRES pipeline. The signal to noise ratio achieved exceeded 5,000 in some parts of the spectra. We discuss how the S\/N obtained compares with what should be theoretically possible and how well we could correct the spectrum for telluric lines using the MOLECFIT package."
