Definition of different tangential shears.

Tangential shears Definitions
γtS$\[\gamma_{\mathrm{t}}^{S}\]$ The true tangential shear
γtobs$\[\gamma_{\mathrm{t}}^{\text {obs }}\]$ The observed tangential shear
δγttheory$\[\delta \gamma_{\mathrm{t}}^{\text {theory }}\]$ PSF-induced residual tangential shear calculated by the theory-based approach (Eq. (10))
δγtobs$\[\delta \gamma_{\mathrm{t}}^{\text {obs }}\]$ PSF-induced residual tangential shear calculated by the observation-based approach (Eq. (11))
γ^tS$\[\hat{\gamma}_{\mathrm{t}}^{S}\]$ The estimator of the true tangential shear calculated by γtobsδγtobs$\[\gamma_{\mathrm{t}}^{\text {obs }}-\delta \gamma_{\mathrm{t}}^{\text {obs }}\]$
γ^tobs$\[\hat{\gamma}_{\mathrm{t}}^{\text {obs }}\]$ The estimator of the observed tangential shear calculated by γtS+δγttheory$\[\gamma_{\mathrm{t}}^{S}+\delta \gamma_{\mathrm{t}}^{\text {theory }}\]$

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
