本文给出了弱透镜簇计数数值研究的主要结果。我们研究了投影密度峰值质量函数的宇宙学标度。我们的主要结论是，投影峰和三维质量函数与宇宙学的比例惊人地接近。这意味着，尽管是从二维场中推导出来的，但弱透镜星团丰度可以用来约束宇宙学，就像其他类型的调查所探测到的三维质量函数一样。
We present the main results of a numerical study of weak lensing cluster counting. We examine the scaling with cosmology of the projected-density-peak mass function. Our main conclusion is that the projected-peak and the three-dimensional mass functions scale with cosmology in an astonishingly close way. This means that, despite being derived from a two-dimensional field, the weak lensing cluster abundance can be used to constrain cosmology in the same way as the three-dimensional mass function probed by other types of surveys.
