We present the first application to real data from the BOSS DR12 dataset of the Extractor procedure (Noda et al., 2017, Nishimichi et al., 2018) to determine the acoustic scale imprinted on Baryonic Acoustic Oscillations (BAO). We show that, being largely insensitive to the broadband shape of the Power Spectrum, this procedure requires a lower number of nuisance parameters than those used by the BOSS collaboration, For non-reconstructed data our analysis improves the accuracy on the acoustic scale by about 20%, while for reconstructed ones we get essentially the same level of accuracy as the BOSS analysis.

从BOSS DR12数据集中提取BAO量表

我们提出了提取程序的BOSS DR12数据集的真实数据的第一个应用程序（Noda等人，2017，Nishimichi等人，2018），以确定压印在重音声振荡（BAO）上的声阶。我们表明，由于对功率谱的宽带形状基本不敏感，因此此过程所需的干扰参数数量少于BOSS合作使用的干扰参数。对于非重建数据，我们的分析将声学尺度的精度提高了约20倍。 ％，而对于重构的，我们获得的精度与BOSS分析基本相同。
