LALSuite is a large collection of gravitational-wave data analysis libraries,
mainly written in C but with high-level bindings for Python.

The main LALSuite documentation can be found at

https://lscsoft.docs.ligo.org/lalsuite/

LALSuite is made up of a number of component libraries, some of which are
utilised by GWpy to provide various extra capabilities.

The full LALsuite can be installed alongside GWpy using
`Conda <https://conda.io>`__
(or `Mamba <https://mamba.readthedocs.io/en/stable/>`__)
or `pip`:

.. tab-set::

    .. tab-item:: Install LALSuite with conda/mamba
        :name: gwpy-install-lalsuite-conda

        .. code-block:: shell

            conda install -c conda-forge lalsuite

    .. tab-item:: Install LALSuite with pip
        :name: gwpy-install-lalsuite-pip

        .. code-block:: shell

            python -m pip install lalsuite

LAL is the base-level library in LALSuite that provides much of the core
functionality.
It's documentation is at

https://lscsoft.docs.ligo.org/lalsuite/lal/

GWpy provides utilities to transform to and from LAL objects
(like the |lal.REAL8TimeSeries|) from/to their GWpy equivalent
(e.g. :class:`gwpy.timeseries.TimeSeries`).

LAL can be installed using `Conda <https://conda.io>`__
(or `Mamba <https://mamba.readthedocs.io/en/stable/>`__)
on Unix systems (not Windows):

.. code-block:: shell
    :name: conda-install-lal
    :caption: Install python-lal with conda

    conda install -c conda-forge python-lal

LALFrame provides a GWF I/O library compatible with LAL series types.
It's documentation is at

https://lscsoft.docs.ligo.org/lalsuite/lalframe/

GWpy utilises the Python bindings for LALFrame on Unix platforms
(Linux and macOS) to provide GWF input/output capabilities.

This optional dependency can be installed using `Conda <https://conda.io>`__
(or `Mamba <https://mamba.readthedocs.io/en/stable/>`__)
on Unix systems (not Windows):

.. code-block:: shell
    :name: conda-install-python-lalframe
    :caption: Install python-lalframe with conda

    conda install -c conda-forge python-lalframe
