Description of CRESST-II data

Abstract

In Phase 2 of CRESST-II 18 detector modules were operated for about two years (July 2013 - August 2015). Together with this document we are publishing data from two detector modules which have been used for direct dark-matter searches. With these data-sets we were able to set world-leading limits on the cross section for spin-independent elastic scattering of dark matter particles off nuclei. We publish the energies of all events within the acceptance regions for dark-matter searches. In addition, we also publish the energies of the events within the electron-recoil band. This data set can be used to study interactions with electrons of CaWO${}_4$. In this document we describe how to use these data sets. In particular, we explain the cut-survival probabilities required for comparisons of models with the data sets.

Text unchanged to v2, new ancillary files added containing simulated data for the sensitivity projections of CRESST-III phase 2 with 1 tonne day exposure, additional information may be found in anc/Proj_CRESST-III-Phase2_README.txt
