We present the Dark Energy Camera All Data Everywhere (DECADE) weak lensing dataset: a catalog of 107 million galaxies noticed by the Dark Energy Camera (DECam) within the northern Galactic cap. This catalog was assembled from public DECam knowledge including survey and normal observing programs. These information were consistently processed with the Dark Energy Survey Data Management pipeline as a part of the DECADE campaign and function the basis 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 collection of detailed research to characterize the catalog, measure any residual systematic biases, and confirm that the catalog is suitable for cosmology analyses. Despite the considerably inhomogeneous nature of the data set, high capacity pruning tool because of it being an amalgamation of assorted observing programs, we find the ensuing catalog has ample quality to yield competitive cosmological constraints.

Measurements of weak gravitational lensing - the deflection of mild from distant sources by the intervening matter distribution between the supply and the observer - present essential constraints on the expansion, evolution, and high capacity pruning tool content of the Universe (Bartelmann & Schneider 2001
