Deep-field Metacalibration
We introduce deep-field metacalibration, a new technique that reduces the pixel noise in metacalibration estimators of weak lensing shear signals by using a deeper imaging survey for calibration. In standard metacalibration, a small artificial shear is applied to the observed images of galaxies in o...
