  "description": "Results of the Search for eV-scale sterile neutrinos with the DeepCore \"golden\" sample in machine readable format. Allows reproduction of Figure 5 of the publication.\n\n<ul>\n\n<li> The file \"wilks_contour_90pct.csv\" contains the 90% contour line in CSV format. The columns \"U\\mu4_sq\" and \"U\\tau4_sq\" correspond to the _squared_ elements of the 3+1 mixing matrix, |U_{&mu;4}|^2 and |U_{&tau;4}|^2, respectively. The contour was drawn assuming that Wilks' theorem holds with two degrees of freedom. The points are ordered by nearest neighbors. </li>\n\n<li> The file \"expected_sensitivity_90pct.csv\" contains the expected sensitivity at 90% CL of the analysis for Asimov data produced at the null hypothesis. The format is identical to that of the result. </li>\n\n<li> The files \"marginalized_umu4_sq.csv\" and \"marginalized_utau4_sq.csv\" contain the marginalized scan of the test statistic over the matrix elements. The column \"Metric Difference\" refers to the delta chi-square metric used in the analysis. Since this metric is a delta chi-square (rather than a likelihood), it should _not_ be multiplied by two when calculating significances. They allow reproduction of the top and right panels of Figure 5 of the publication. </li>\n\n<li> The file \"real_data_wilks_contours_reprod_mar_2025_best_fit_points.tab\" contains the best-fit values of all free nuisance parameters in a |U_{&mu;4}|^2 and |U_{&tau;4}|^2 scan. </li>\n\n<li> The file \"real_data_wilks_contours_reprod_mar_2025_metric_diff.tab\" contains the …",
