质量可观测标度关系的不确定性是目前基于星系团的宇宙学的限制因素。弱引力透镜可以提供直接的质量校准，降低质量的不确定性。我们提出了新的地基弱透镜观测的19个南极望远镜（SPT）选定的星系团在红移和联合收割机他们结合以前报道的空间观测的13个星系团在红移约束与Sunyaev-Zel 'dovich效应（SZE），集群气体质量\mgas，\yx，\mgas\和X射线温度的产品的集群质量标度关系。我们扩展了以前使用的尺度关系和宇宙学约束的分析框架，从SPT选择集群利用弱透镜信息。我们介绍了一种新的方法来估计背景星系的有效平均红移分布，并量化了一些影响弱透镜模型的系统误差。这些误差包括校准Navarro-Frenk-白色剖面与使用人体模拟的减小剪切拟合所引起的偏差。我们对分析进行盲化以避免确认偏差。我们能够将系统的不确定性限制在5.6%的集群质量（68%的置信度）。我们对质量-X射线可观测的标度关系参数的约束与早期研究获得的参数一致，我们对质量-SZE标度关系的约束与最近SPT-SZ宇宙学分析中使用的基于模拟的先验一致。我们现在可以取代外部质量校准先验使用在以前的SPT-SZ宇宙学研究与直接，内部校准获得相同的集群。
Uncertainty in the mass-observable scaling relations is currently the limiting factor for galaxy cluster based cosmology. Weak gravitational lensing can provide a direct mass calibration and reduce the mass uncertainty. We present new ground-based weak lensing observations of 19 South Pole Telescope (SPT) selected clusters at redshiftsand combine them with previously reported space-based observations of 13 galaxy clusters at redshiftsto constrain the cluster mass scaling relations with the Sunyaev-Zel'dovich effect (SZE), the cluster gas mass \mgas, and \yx, the product of \mgas\ and X-ray temperature. We extend a previously used framework for the analysis of scaling relations and cosmological constraints obtained from SPT-selected clusters to make use of weak lensing information. We introduce a new approach to estimate the effective average redshift distribution of background galaxies and quantify a number of systematic errors affecting the weak lensing modelling. These errors include a calibration of the bias incurred by fitting a Navarro-Frenk-White profile to the reduced shear using-body simulations. We blind the analysis to avoid confirmation bias. We are able to limit the systematic uncertainties to 5.6% in cluster mass (68% confidence). Our constraints on the mass--X-ray observable scaling relations parameters are consistent with those obtained by earlier studies, and our constraints for the mass--SZE scaling relation are consistent with the simulation-based prior used in the most recent SPT-SZ cosmology analysis. We can now replace the external mass calibration priors used in previous SPT-SZ cosmology studies with a direct, internal calibration obtained on the same clusters.
