Open Data — PandaX-4T (nuDM)
Overview
| Item | Value |
|---|---|
| Experiment | PandaX-4T |
| Energy range | 20 – 2800 keV |
| Bin width | 4 keV (695 bins) |
| Format | CSV |
Each CSV has columns: E_low_keV, E_high_keV, E_center_keV, run0, run1.
All spectra are normalised to unit integral (nominal PDF), except bkg_model.csv which gives the nominal background with nominal values.
All PDFs have been convolved with the detector energy response function; see the paper for details.
