Wood Ranger Power Shears Make Trimming Hedges Easy

SandraBell

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 noticed by the Dark Energy Camera (DECam) in the northern Galactic cap. The catalog derives from a large number of disparate observing packages and is due to this fact more inhomogeneous across the sky in comparison with present lensing surveys. First, we use simulated information-vectors to indicate the sensitivity of our constraints to different evaluation choices in our inference pipeline, including 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 info and is carried out in a completely consistent method: for every subset of the information, we re-derive the photometric redshift estimates, shear calibrations, survey transfer functions, the data vector, measurement covariance, and eventually, the cosmological constraints. Our results show that present evaluation strategies for weak lensing cosmology can be pretty resilient towards inhomogeneous datasets.
