Logbook of spectroscopic observations.
Frequency list and statistics from a Fourier analysis with iterative nonlinear updates of the parameters.
Binary fit to a selection of spectral lines. In grey, the average of all observed HARPS spectra of HD 50230 is plotted. Dashed black lines denote the contributions of the separate companions, the solid black line shows the obtained binary fit. Note that due to the simultaneous fitting of the continuum with the lines, the line continuum level can be off if the line does not fit well (i.e., the average quadratic distance between the observed and synthetic line profile is minimised). The fit consists of a primary component with Teff = 18 500 K and log g = 4.0 (cgs), and Teff = 15 000 K and log g = 4.0 (cgs) for the secondary.
