This pull request adds support for simulating correlated noise across detectors, both in the documentation and in the simulation code. It introduces new APIs and parameters for specifying inter-detector noise correlations, including common-mode and arbitrary correlation matrix models. The documentation is updated with detailed explanations and usage examples.
Correlated noise simulation support:
add_correlated_noisefunction and exposed it in the package's public API (__init__.py). [1] [2]add_noisemethod insimulations.pyto support a newnoise_type='correlated'mode, with acorrelationparameter allowing users to specify groupings, correlation matrices, and other options. [1] [2] [3]Documentation improvements:
noise.rstdocumentation with a new section explaining correlated noise, including mathematical models, parameter descriptions, and code examples for both the common-mode and Cholesky models.These changes enable more realistic detector noise simulations, especially for experiments where noise is not fully independent across detectors.
