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 data including survey and commonplace observing programs. These data had been persistently processed with the Dark Energy Survey Data Management pipeline as part of the DECADE campaign and serve as the premise 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 suitable for cosmology analyses. Despite the significantly inhomogeneous nature of the information set, because of it being an amalgamation of various observing applications, we discover the resulting catalog has adequate quality to yield aggressive cosmological constraints.

Measurements of weak gravitational lensing - the deflection of gentle from distant sources by the intervening matter distribution between the source and the observer - provide necessary constraints on the growth, evolution, and content of the Universe (Bartelmann & Schneider 2001
