gwexpy 0.1.1

A comprehensive Python package for Gravitational Wave experimental data analysis, extending GWpy with strict unit handling and advanced spectral methods.

gwexpy: GWpy Expansions for Experiments

gwexpy is an extension library for GWpy for experimental physics and gravitational-wave data analysis. It adds matrix-aware containers, field operations, fitting workflows, expanded I/O, and interoperability layers while staying close to GWpy-style analysis.

Install

git clone https://github.com/tatsuki-washimi/gwexpy.git
cd gwexpy
python -m pip install -e .

Why gwexpy?

• Matrix-native analysis: TimeSeriesMatrix, FrequencySeriesMatrix, and SpectrogramMatrix support batch processing, transfer functions, and multichannel workflows.
• Physics-oriented containers: ScalarField, VectorField, and TensorField extend analysis beyond simple series into structured field data.
• Practical workflows: fitting, noise hunting, time-frequency analysis, and interoperability are exposed as user-facing workflows rather than isolated utilities.
• Broad interoperability and I/O: gwexpy bridges scientific Python tools and extends format coverage beyond core GWpy workflows.

Quick Start

import numpy as np
import gwexpy
from gwexpy.timeseries import TimeSeries, TimeSeriesList

gwexpy.register_all()

ts1 = TimeSeries(np.arange(8.0), dt=1.0, name="A")
ts2 = TimeSeries(np.arange(8.0) * 2.0, dt=1.0, name="B")
matrix = TimeSeriesList([ts1, ts2]).to_matrix()
asd = matrix.asd(fftlength=2.0)
print(matrix.shape)

For fitting, I/O, interoperability, and notebook-based workflows, start from the docs hub or the tutorial index above.
