Potential impact of noise correlation in next-generation gravitational wave detectors — Data release

Paper Reference:

This dataset accompanies the preprint "Potential impact of noise correlation in next-generation gravitational wave detectors" (arXiv:2407.08728), which presents the methodology and results associated with this data. A peer-reviewed version is forthcoming.

Description:

This dataset contains the raw outputs from the Fisher analysis. The data was generated as part of research on the impact of noise correlation in parameter estimation of gravitational-wave transients for next-generation gravitational wave detectors. It includes:

1. BBH_{corr_coef}_fhigh10_{network}_snr.npy: A 1D array of the signal-to-noise-ratio of the injections.
2. BBH_{corr_coef}_fhigh10_{network}_cov.npy: A 3D array of the Fisher covariance matrix for the injections. The first dimension is the injection. The second and the third dimensions are the covariance matrix.
3. BBH_{corr_coef}_fhigh10_{network}_errs.npy: A 2D array of the Fisher standard deviation for the injections. The first dimension is the injection. The second dimension is the standard deviation.

Definition of the labels:

• corr_coef: The correlation coefficient. E.g. 0p1 indicates a correlation coefficient of 0.1.
• network: The detector network configuration.
  • LA1: A detector located at Limburg.
  • LM1: A detector located at Limburg with a 45-degree misalignment with LA1.
  • S1: A detector located at Sardinia.
  • H1: A detector located at Hanford.

File Formats:

The dataset is provided in NPY format. The files can be read using the numpy function np.load.

Usage Notes:

Users are encouraged to refer to the associated paper for details on the data generation process and its interpretation. Example scripts for loading and processing the data are included in the Github repository.
