Title: Survey geometry and the internal consistency of recent cosmic shear measurements

Abstract

We explore the impact of an update to the typical approximation for the shape noise term in the analytic covariance matrix for cosmic shear experiments that assumes the absence of survey boundary and mask effects. We present an exact expression for the number of galaxy pairs in this term based on the survey mask, which leads to more than a factor of three increase in the shape noise on the largest measured scales for the Kilo-Degree Survey (KiDS-450) real-space cosmic shear data. We compare the result of this analytic expression to several alternative methods for measuring the shape noise from the data and find excellent agreement. This update to the covariance resolves any internal model tension evidenced by the previously large cosmological best-fitting χ2 for the KiDS-450 cosmic shear data. The best-fitting χ2 is reduced from 161 to 121 for 118 degrees of freedom. We also apply a correction to how the multiplicative shear calibration uncertainty is included in the covariance. This change shifts the inferred amplitude of the correlation function to higher values. In conclusion, we find that this improves agreement of the KiDS-450 cosmic shear results with Dark Energy Survey Year 1 and Planck results.

Figure 1 Figure 1: The impact of updates to the KiDS-450 covariance diagonal. Upper panel: The ratio of the true shape noise term to the geometric approximation in the (1,1) tomographic bin pair, which has a nominal range of $z$ = 0.1 to 0.3, from (a) the variance of $ξ$− (Var($ξ$+) ismore » also consistent) measured from 1000 random rotations of the KiDS-450 shape catalogue (blue circles), (b) replacing $n$eff with the measured $N$p($θ$) in Eq. 5 (red squares), and (c) an analytic prediction for $N$p($θ$) from the survey mask in Eq. 6 with (solid) and without (dotted) source clustering (green lines). We compare the impact for a DES Y1-like survey footprint. For KiDS-450, the correction increases the shape noise by up to a factor of 3.5 on the largest measured scales, which corresponds to a maximum factor of 1.4 for DES Y1. On the smallest scales, the shape noise is slightly decreased due to source clustering. Lower panel: The ratio of the final corrected covariance to the original covariance for $ξ$+ (black stars) and $ξ$− (blue triangles). Only angular scales used in the H17 analysis are shown. We include the (4,4) tomographic bin pair with nominal range $z$ = 0.7 to 0.9 for comparison (open symbols).« less
