### Calibration of weak-lensing shear in the Kilo-Degree Survey

Abstract:

We describe and test the pipeline used to measure the weak lensing shear signal from the Kilo Degree Survey (KiDS). It includes a novel method of self-calibration' that partially corrects for the effect of noise bias. We also discuss the weight bias' that may arise in optimally-weighted measurements, and present a scheme to mitigate that bias. To study the residual biases arising from both galaxy selection and shear measurement, and to derive an empirical correction to reduce the shear bias...
