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) in the northern Galactic cap. This catalog was assembled from public DECam knowledge together with survey and commonplace observing programs. These knowledge were persistently processed with the Dark Energy Survey Data Management pipeline as part of the DECADE 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 present a suite of detailed research 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, attributable to it being an amalgamation of various observing applications, we discover the resulting catalog has enough high quality to yield aggressive cosmological constraints.

Measurements of weak gravitational lensing - the deflection of mild from distant sources by the intervening matter distribution between the source and the observer - provide essential constraints on the expansion, evolution, and content material of the Universe (Bartelmann & Schneider 2001 \ No newline at end of file
