How Wood Ranger Power Shears Turned Yard Work Into a Breeze

JorgeKnott

We present the pipeline for the cosmic shear evaluation of the Dark Energy Camera All Data Everywhere (DECADE) weak lensing dataset: a catalog consisting of 107 million galaxies observed by the Dark Energy Camera (DECam) within the northern Galactic cap. The catalog derives from a lot of disparate observing packages and is therefore extra inhomogeneous across the sky in comparison with present lensing surveys. First, we use simulated information-vectors to indicate the sensitivity of our constraints to totally different evaluation selections in our inference pipeline, together with sensitivity to residual systematics. Next we use simulations to validate our covariance modeling for inhomogeneous datasets. This is completed for forty-six subsets of the information and is carried out in a completely constant manner: for each subset of the information, we re-derive the photometric redshift estimates, shear calibrations, survey switch functions, the information vector, measurement covariance, and eventually, the cosmological constraints. Our outcomes present that existing evaluation methods for weak lensing cosmology may be pretty resilient in the direction of inhomogeneous datasets.
