Description


We have developed two independent methods to measure the one-dimensional power spectrum of the transmitted flux in the Lyman-{alpha} forest. The first method is based on a Fourier transform, and the second on a maximum likelihood estimator. The two methods are independent and have different systematic uncertainties. The determination of the noise level in the data spectra was subject to a novel treatment, because of its significant impact on the derived power spectrum. We applied the two methods to 13,821 quasar spectra from SDSS-III/BOSS DR9 (Baryon Oscillation Spectroscopic Survey, BOSS, 2013AJ....145...10D) selected from a larger sample of over 60,000 spectra on the basis of their high quality, large signal-to-noise ratio, and good spectral resolution. The power spectra measured using either approach are in good agreement over all twelve redshift bins from <z>=2.2 to <z>=4.4, and scales from 0.001(km/s)^-1^ to 0.02(km/s)^-1^. We determine the methodological and instrumental systematic uncertainties of our measurements.
