Notation

• erc, nrc, and irc in the file names indicate the calibration policy adopted.
  • erc stands for electron-recoil-compatible with the DAMA experiment. It adopted the linear calibration pivoted at 60 keV gamma-ray. It is identical to $\mathrm{keV_{ee}}$ in the paper.
  • nrc stands for (sodium)-nuclear-recoil-compatible with the DAMA experiment. It calibrates considering the different quenching factors (for Na-recoil) of two experiments, DAMA and COSINE-100. Dividing them by 0.3 gives the energy in $\mathrm{keV_{nr}}$ in the paper.
  • irc stands for iodine-(nuclear)-recoil-compatible with the DAMA experiment. It calibrates considering the different quenching factors (for I-recoil) of two experiments, DAMA and COSINE-100. Dividing them by 0.09 gives the energy in $\mathrm{keV_{nr,~I}}$ in the paper.
  • Examples
    • erc1-3 indicates 1-3 $\mathrm{keV_{ee}}$ (linearly-calibrated energy unit).
    • erc2-6 indicates 2-6 $\mathrm{keV_{ee}}$ (linearly-calibrated energy unit).
    • nrc2-6 indicates 6.7-20 $\mathrm{keV_{nr}}$ ($2 \div 0.3$ gives 6.7, $6 \div 0.3$ gives 20). It corresponds to 2-6 keV in the DAMA detectors.
    • irc2-6 indicates 22.2-66.7 $\mathrm{keV_{nr,~I}}$ ($2 \div 0.09$ gives 22.2). It corresponds to 2-6 keV in the DAMA detectors.
• Event rate unit
  • For erc calibration, the event rates, and modulation amplitudes are represented in the unit of “counts/day/kg/$\mathrm{keV_{ee}}$”. It corresponds to the so-called DRU, daily rate unit.
  • For nrc calibration, the event rates, and modulation amplitudes are represented in the unit of “counts/day/kg/units of (3.3 $\mathrm{keV_{nr}}$)”. The weird constant 3.3 makes the resulting numbers to be identical to the numbers in DRU.
  • For irc calibration, the event rates, and modulation amplitudes are represented in the unit of “counts/day/kg/units of (11 $\mathrm{keV_{nr, I }}$)”. The weird constant 11 makes the resulting numbers to be identical to the numbers in DRU.
