Collection of observed modulation rates by NaI experiments (+global average) as of the end of 2021 (in svg and png). The light bands indicate 1sigma uncertainty and the darker bands 2sigma.

Values are:

2-6 keV region

DAMA [1]: 0.0095 +/- 0.0008 dru

COSINE [2]: 0.0050 +/- 0.0047 dru

ANAIS [3]: 0.0003 +/- 0.0037 dru

Weighted av: 0.0090 +/- 0.0008 dru

1-6 keV region

DAMA [1]: 0.0105 +/- 0.0011 dru

COSINE [2]: 0.0067 +/- 0.0042 dru

ANAIS [3]: -0.0034 +/- 0.0042 dru

Weighted av: 0.0094 +/- 0.0010 dru

Similar to above in the 1-6 keV region, but we include the observed rate for a selection of different quenching factors and the same DM model.

Purpose is to demonstrate how much an observation might change given different crystal dependent quenching factors. For this mass and cross section, results are produced ranging an order of magnitude, allowing for observations within 1sigma of both ANAIS and DAMA, assuming particular crystal QFs.
