WebJun 7, 2024 · Metacalibration is a method to calibrate weak lensing shear measurements. It involves creating artifically sheared images. This means deconvolving, shearing, and … WebMetacalibration. applied to Euclid & Roman. The complexity and the realism in the image simulations must be increase to calibrate shear as the lensing surveys get better and the precision in our results improve. Metacalibration is a new player in the field which attempts to solve this problem by calibrating shear from the observed image itself.
