Mitigating the Noise-Source Coupling Effect in Shear Measurement
HeKun Li, Jun Zhang
Sub-percent level accuracy in shear measurement is required by the Stage-IV weak lensing surveys. One important challenge is about suppressing the shear bias on source images of lo…

Avoiding the Geometric Boundary Effect in Shear Measurement
Haoran Wang, Jun Zhang, Hekun Li +1
In image processing, source detections are inevitably affected by the presence of the geometric boundaries in the images, including the physical boundaries of the CCD, and the boun…

Towards a Bias-Free Selection Function in Shear Measurement
Hekun Li, Jun Zhang, Dezi Liu +5
Sample selection is a necessary preparation for weak lensing measurement. It is well-known that selection itself may introduce bias in the measured shear signal. Using image simula…
