gwmock-noise 0.1.4

A Python package for simulating gravitational wave detector noise.

gwmock-noise

A Python package for simulating gravitational-wave detector instrumental noise (colored and correlated models, lines, glitches, optional Schumann-resonance coupling, and CLI-driven batch runs).

Documentation

Published docs (user guide and API reference):

https://leuven-gravity-institute.github.io/gwmock-noise/

To build and preview locally (requires the docs dependency group):

uv sync --group docs
uv run zensical serve

Then open http://127.0.0.1:8000.

Quick start

Install

uv venv --python 3.12
source .venv/bin/activate  # Windows: .venv\Scripts\activate
uv pip install gwmock-noise

Optional extras (declared in pyproject.toml):

• gwmock-noise[gwpy] — GWpy-based helpers (for example GWpyAdapter)
• gwmock-noise[frame] — GWF frame output (FrameWriter / GWpy GWF stack)
• gwmock-noise[gengli] — gengli-backed blip glitches (GengliBlipGlitch)

CLI

Create a TOML (or YAML/JSON) config and run:

gwmock-noise simulate examples/noise_config_example.toml

To turn a GravitySpy CSV export into a gengli population file:

gwmock-noise build-blip-glitch-table --gravity-spy-csv gravity_spy.csv --out glitches.h5

See examples/noise_config_example.toml and the noise simulation guide for fields and output layout.

Python API

from pathlib import Path

from gwmock_noise import DefaultNoiseSimulator, NoiseConfig, OutputConfig

config = NoiseConfig(
    detectors=["H1", "L1"],
    duration=4.0,
    sampling_frequency=4096.0,
    output=OutputConfig(directory=Path("output"), prefix="noise"),
    seed=42,
)
result = DefaultNoiseSimulator().run(config)
for detector, path in result.output_paths.items():
    print(detector, "->", path)

For PSD/CSD-driven colored noise, spectral lines, glitches, and streaming behavior, use the same NoiseConfig fields described in the user guide and API reference. For stateful continuation across chunk boundaries, prefer the public open_stream(...) helper over reseeding separate runs.

The gengli backend plugs into the same glitches= surface:

from pathlib import Path

from gwmock_noise import (
    DefaultNoiseSimulator,
    GengliBlipGlitch,
    LogNormalAmplitudeDistribution,
    NoiseConfig,
    OutputConfig,
)

config = NoiseConfig(
    detectors=["L1"],
    duration=8.0,
    psd_file=Path("noise_psd.txt"),
    glitches=[
        GengliBlipGlitch.from_population_file(
            "glitches.h5",
            rate=0.25,
            psd_file=Path("noise_psd.txt"),
            amplitude_distribution=LogNormalAmplitudeDistribution(mean=1.0, std=0.0),
        )
    ],
    output=OutputConfig(directory=Path("output"), prefix="gengli"),
)
DefaultNoiseSimulator().run(config)

NoiseConfig.psd_file also accepts bundled Einstein Telescope preset names, so you can use psd_file="ET_10_full_cryo_psd" without managing the PSD file yourself. Available presets are ET_D_psd, ET_10_HF_psd, ET_10_full_cryo_psd, ET_15_HF_psd, ET_15_full_cryo_psd, ET_20_HF_psd, and ET_20_full_cryo_psd. Local paths and HTTP(S) URLs remain supported too (for remote sources, use .txt or .csv).

Installation

We recommend using uv to manage virtual environments for installing gwmock-noise.

If you don't have uv installed, you can install it with pip. See the project pages for more details:

• Install via pip: pip install --upgrade pip && pip install uv
• Project pages: uv on PyPI | uv on GitHub
• Full documentation and usage guide: uv docs

Requirements

• Python 3.12 or higher
• Operating System: Linux, macOS, or Windows

Note: The package is built and tested against Python 3.12–3.14. When creating a virtual environment with uv, specify the Python version to ensure compatibility: uv venv --python 3.12 (replace 3.12 with your preferred version in the 3.12–3.14 range). This avoids potential issues with unsupported Python versions.

Install from PyPI

The recommended way to install gwmock-noise is from PyPI:

# Create a virtual environment (recommended with uv)
uv venv --python 3.12
source .venv/bin/activate  # On Windows: .venv\Scripts\activate
uv pip install gwmock-noise

Install from Source

For the latest development version:

git clone [e-mail]:Leuven-Gravity-Institute/gwmock-noise.git
cd gwmock-noise
# Create a virtual environment (recommended with uv)
uv venv --python 3.12
source .venv/bin/activate  # On Windows: .venv\Scripts\activate
uv sync

Development Installation

To set up for development (linting, tests, and docs tooling live in uv dependency groups, not [project.optional-dependencies]):

git clone [e-mail]:Leuven-Gravity-Institute/gwmock-noise.git
cd gwmock-noise

# Create a virtual environment (recommended with uv)
uv venv --python 3.12
source .venv/bin/activate  # On Windows: .venv\Scripts\activate
uv sync --group dev --group docs

# Install pre-commit hooks
uv run pre-commit install

Verify Installation

Check that gwmock-noise is installed correctly:

gwmock-noise --help

python -c "import gwmock_noise; print(gwmock_noise.__version__)"
