Searching for dark matter with a spin-based interferometer

This is experimental data related to the article "Searching for dark matter with a spin-based interferometer" (https://doi.org/10.48550/arXiv.2309.16000).

The data consists of discrete Fourier transforms of 25-h long time series recorded by self-compensating K-Rb-3He comagnetometers in Kraków, Poland and Mainz, Germany.

The spectra are calibrated assuming neutron coupling referring to Table 1 in Mikhail Padniuk's et al. article "Response of atomic spin‑based sensors to magnetic and nonmagnetic perturbations" (https://doi.org/10.57903/UJ/J33SMI). Calibration function parameters are also available in each file.

本数据集为与论文《基于自旋基干涉仪（spin-based interferometer）搜寻暗物质》（DOI: 10.48550/arXiv.2309.16000）相关的实验数据。该数据集包含由波兰克拉科夫与德国美因茨的自补偿式钾-铷-氦3共磁强计（comagnetometer）记录的25小时时长的时间序列的离散傅里叶变换结果。本次频谱校准基于中子耦合假设，校准依据参考自Mikhail Padniuk等人发表的论文《原子自旋基传感器对磁与非磁扰动的响应》（https://doi.org/10.57903/UJ/J33SMI）中的表1。每个数据文件中均附带校准函数参数。
