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 knowledge including survey and normal observing packages. These information have been constantly processed with the Dark Energy Survey Data Management pipeline as part of the DECADE marketing campaign and serve as the idea of the DECam Local Volume Exploration survey (DELVE) Early Data Release 3 (EDR3). We apply the Metacalibration measurement algorithm to generate and calibrate galaxy shapes. We current a collection of detailed studies to characterize the catalog, measure any residual systematic biases, and confirm that the catalog is appropriate for cosmology analyses. Despite the considerably inhomogeneous nature of the data set, because of it being an amalgamation of various observing programs, we find the resulting 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, Wood Ranger Tools and content of the Universe (Bartelmann & Schneider 2001
