Scatter and bias in weak lensing selected clusters

Understand

We examine scatter and bias in weak lensing selected clusters, employing both an analytic model of dark matter haloes and numerical mock data of weak lensing cluster surveys.

• We pay special attention to effects of the diversity of dark matter distributions within clusters.
• We find that peak heights of the lensing convergence map correlates rather poorly with the virial mass of haloes.
• The correlation is tighter for the spherical overdensity mass with a higher mean interior density.
