Figure 6: Left panel: global broadening function of Altair reconstructed from about 650 lines. Error bars corresponding to a signal-to-noise ratio of 1000 are overplotted. Right panel: Fourier transform of the reconstructed broadening function ( left panel) with its error bars. Note the logarithmic scale on the y-axis. |
