Data sets IceCube IceCube DeepCore Atmospheric Sterile neutrinos Curated

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.

<ul>

<li> The file "wilkscontour90pct.csv" contains the 90% contour line in CSV format. The columns "U\mu4sq" and "U\tau4sq" 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>

<li> The file "expectedsensitivity90pct.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>

<li> The files "marginalizedumu4sq.csv" and "marginalizedutau4sq.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>

<li> The file "realdatawilkscontoursreprodmar2025bestfitpoints.tab" contains the best-fit values of all free nuisance parameters in a |U{&mu;4}|^2 and |U_{&tau;4}|^2 scan. </li>
