Propagating spatially varying multiplicative shear bias to cosmological parameter estimation for stage-IV weak-lensing surveys

We consider the bias introduced by a spatially varying multiplicative shear bias (<i>m</i>-bias) on tomographic cosmic shear angular power spectra. To compute the bias in the power spectra, we estimate the mode-coupling matrix associated with an <i>m</i>-bias map using a comp...
