How Wood Ranger Power Shears Turned Yard Work Into a Breeze
We measure weak lensing cosmic shear power spectra from the three-year galaxy shear catalog of the Hyper Suprime-Cam (HSC) Subaru Strategic Program imaging survey. 1800 due to theoretical uncertainties in our modeling of those nonlinear scales (primarily based on tests described in Sections V.2.1 and V.3). This offers us six multipole bins that we use in our fiducial analysis, from the 17 that we originally measure. We derive the covariance matrix of our cosmic shear power spectra using the mock catalogs described in Section II.5. We accomplish that by measuring the cosmic shear power spectra, following the identical methodology as our measurement from information, from all 1404 realizations of the mocks, and then utilizing these 1404 power spectra to compute the covariance matrix. Gaussian and non-Gaussian components. We treat these mock catalogs precisely like our actual data. We first measure the ability spectra from every mock catalog on a field-by-field foundation.
