使用大尺度结构有效场论（EFTBOSS）的单回路预测的BOSS DR 12功率谱的完整形状的分析导致了对$\Lambda$CDM模型的扩展的新约束，例如早期暗能量（EDE），其已被建议作为对“哈勃张力”的解决方案。在本文中，我们重新评估的EFTBOSS对EDE的约束力，根据校正BOSS窗口功能的规范化。总的来说，我们发现，从EFTBOSS对EDE的约束被削弱，并代表一个小的变化相比，从普朗克和传统的BAO/$f\sigma_8$测量的约束。普朗克数据与EFTBOSS的结合提供了一个在95% C. L.时EDE $f_{\rm EDE}<0.083$的最大分数贡献的界限。（与不正确归一化的$<0.054$和没有完整形状数据的$<0.088$相比），哈勃张力降低到2.1 σ $。然而，仅用阿塔卡玛宇宙学望远镜的数据进行分析所支持的更极端的模型不受EFTBOSS数据的青睐。我们还表明，更新的万神殿+Ia型超新星分析可以稍微增加对EDE的限制。然而，SH 0 ES对SN 1a星等的校正强烈地增加了对EDE的偏好，使其超过5 σ，在红移z_c=4365^{+3000}_{-1100}$附近产生f_{\rm EDE}\sim 0.12^{+0.03}_{-0.02}$。我们的结果表明，EFTBOSS数据（单独或与普朗克数据相结合）不排除哈勃张力的EDE分辨率。
Analyses of the full shape of BOSS DR12 power spectrum using the one-loop prediction from the Effective Field Theory of Large-Scale Structure (EFTBOSS) have led to new constraints on extensions to the $\Lambda$CDM model, such as Early Dark Energy (EDE) which has been suggested as a resolution to the"Hubble tension". In this paper, we re-assess the constraining power of the EFTBOSS on EDE in light of a correction to the normalization of BOSS window functions. Overall we find that constraints from EFTBOSS on EDE are weakened, and represent a small change compared to constraints from Planck and the conventional BAO/$f\sigma_8$ measurements. The combination of Planck data with EFTBOSS provides a bound on the maximal fractional contribution of EDE $f_{\rm EDE}<0.083$ at 95% C.L. (compared to $<0.054$ with the incorrect normalization, and $<0.088$ without full-shape data) and the Hubble tension is reduced to $2.1\sigma$. However, the more extreme model favored by an analysis with just data from the Atacama Cosmology Telescope is disfavored by the EFTBOSS data. We also show that the updated Pantheon+ Type Ia supernova analysis can slightly increase the constraints on EDE. Yet, the inclusion of the SN1a magnitude calibration by SH0ES strongly increases the preference for EDE to above $5\sigma$, yielding $f_{\rm EDE}\sim 0.12^{+0.03}_{-0.02}$ around the redshift $z_c=4365^{+3000}_{-1100}$. Our results demonstrate that EFTBOSS data (alone or combined with Planck data) do not exclude the EDE resolution of the Hubble tension.
