Inhomogeneous systematic signals in cosmic shear observations
Jacek Guzik, Gary Bernstein
We calculate the systematic errors in the weak gravitational lensing power spectrum which would be caused by spatially varying calibration (i.e. multiplicative) errors, such as mig…

Systematic errors in weak lensing: application to SDSS galaxy-galaxy weak lensing
Rachel Mandelbaum, Christopher M. Hirata, Uros Seljak +6
Weak lensing is emerging as a powerful observational tool to constrain cosmological models, but is at present limited by an incomplete understanding of many sources of systematic e…
