Remark on the Swarm data residual distribution

Abstract In Khokhlov & Hulot (2017), we addressed non-Gaussian shapes of histograms of quantities that related to uncertainties in data. We showed that such non-Gaussian features are very likely the result of a mixture of statistical distributions; the presentation there was mainly qualitative and related to various geomagnetic data. In this short remark, we use the Swarm data and present the natural quantitative description of the data distribution and hence suggest additional data control. Such an approach is also applicable in more general situations.
