Signs of Sulphur fractionation under high magnetic field strength

This dataset contains the analysis materials associated with the manuscript "Signs of Sulphur fractionation under high magnetic field strength". The record contains files used to analyse sulphur fractionation and its dependence on magnetic field strength in solar active regions using Hinode/EIS observations and PFSS-based magnetic connectivity analysis. The analysis is based on nine Hinode/EIS rasters and four diagnostic line pairs: Si X 258.37 Å / S X 264.23 Å S XI 188.68 Å / Ar XI 188.81 Å Ca XIV 193.87 Å / Ar XIV 194.40 Å Fe XVI 262.98 Å / S XIII 256.69 Å The main result is that low-FIP elements, including sulphur, show decreasing relative abundance above approximately 150 G relative to Ar, while no clear dependence on loop length is found. The Hinode/EIS level-1 data used in this study are publicly available from the Naval Research Laboratory Hinode/EIS database.
