We current the Dark Energy Camera All Data Everywhere (DECADE) weak lensing dataset: a catalog of 107 million galaxies observed by the Dark Energy Camera (DECam) in the northern Galactic cap. This catalog was assembled from public DECam data together with survey and normal observing programs. These knowledge have been persistently processed with the Dark Energy Survey Data Management pipeline as a part of the DECADE marketing campaign and function the premise of the DECam Local Volume Exploration survey (DELVE) Early Data Release three (EDR3). We apply the Metacalibration measurement algorithm to generate and calibrate galaxy shapes. We current a set of detailed research to characterize the catalog, measure any residual systematic biases, and verify that the catalog is appropriate for cosmology analyses. Despite the significantly inhomogeneous nature of the data set, resulting from it being an amalgamation of various observing packages, we find the resulting catalog has enough quality to yield aggressive cosmological constraints.

Measurements of weak gravitational lensing - the deflection of light from distant sources by the intervening matter distribution between the source and quick garden trimming the observer - present important constraints on the expansion, evolution, and content material of the Universe (Bartelmann & Schneider 2001
