Description
We developed a new shear measurement pipeline in the Kilo-Degree Survey (KiDS) collaboration, MetaCalibration, which is robust as it is less sensitive to the morphology of observed galaxies. In the KiDS-1000 cosmic shear analysis, the MetaCalibration pipeline increased 28 percent constraining power on the cosmological parameter ($S_8$) compared to the fiducial pipeline, lensfit, because of the higher source number density. With the success of the new pipeline, we continue our cosmic shear analysis with the final release of Legacy data from KiDS. As the KiDS Legacy cosmic shear analysis using the lensfit catalog claims no tension with the Planck constraint, checking the result with an independent shear catalog is valuable. In this analysis with MetaCabliration, we further optimize star selection, photo-z calibration, and the image stacking process with updated astrometry.
