Summary of the contribution to the bias and its uncertainties from the different effects for the two S/Nflux cuts used in this paper.
Contribution | S/Nflux > 10 | S/Nflux > 7 | ||
---|---|---|---|---|
m1 | m2 | m1 | m2 | |
Residual bias after CANDELS-like calibration | 0.0010 ± 0.0040 | −0.0023 ± 0.0043 | −0.0032 ± 0.0049 | −0.0047 ± 0.0045 |
Bias from extra faint V606 > 27.5 galaxies | −0.0037 ± 0.0055 | −0.0060 ± 0.0065 | −0.0061 ± 0.0046 | −0.0070 ± 0.0041 |
Bright cluster galaxy contribution (z > 0.7): Shape measurement bias | 0.0048 ± 0.0038 | 0.0025 ± 0.0040 | ||
Bright cluster galaxy contribution (z > 0.7): Selection bias | 0.0053 ± 0.0019 | 0.0060 ± 0.0029 | ||
Other modelling uncertainties (simulation mismatch effects) | ±0.0128 | ±0.0130 | ±0.0126 | ±0.0131 |
Total residual bias + uncertainty | 0.0074 ± 0.0151 | 0.0017 ± 0.0157 | −0.0008 ± 0.0151 | −0.0032 ± 0.0153 |
Notes. We present a separated bias for each shear component for all effects except for the light contamination due to bright galaxies, since that is calculated from the tangential shear, which depends on both components. The modelling errors include the uncertainties related to variations in the PSF shape and the galaxy light profile distributions.
