我们提出了加拿大-法国-夏威夷望远镜透镜调查(CFHTLenS),准确地确定了一个弱的引力透镜信号,从完整的154 deg 2深多色数据获得的CFHT遗产调查。大尺度结构的弱引力透镜被广泛认为是宇宙学中最强大但技术上最具挑战性的探索之一。我们概述了CFHTLenS分析管道,描述了从原始像素数据到透镜剪切和光度红移测量的链的每一步是如何以及为什么与以前对相同数据子集的分析相比进行了修改和改进。我们提出了一种新的方法来识别数据,这有助于我们的样本不可忽略的污染,并量化所需的校准水平的调查。通过一系列的宇宙学不敏感的测试,我们证明了由此产生的宇宙剪切信号的鲁棒性,提出了一个科学准备剪切和光度红移目录,为未来的开发。
We present the Canada–France–Hawaii Telescope Lensing Survey (CFHTLenS) that accurately determines a weak gravitational lensing signal from the full 154 deg2of deep multicolour data obtained by the CFHT Legacy Survey. Weak gravitational lensing by large-scale structure is widely recognized as one of the most powerful but technically challenging probes of cosmology. We outline the CFHTLenS analysis pipeline, describing how and why every step of the chain from the raw pixel data to the lensing shear and photometric redshift measurement has been revised and improved compared to previous analyses of a subset of the same data. We present a novel method to identify data which contributes a non-negligible contamination to our sample and quantify the required level of calibration for the survey. Through a series of cosmology-insensitive tests we demonstrate the robustness of the resulting cosmic shear signal, presenting a science-ready shear and photometric redshift catalogue for future exploitation.
