-SWIFTGalaxy is a module that extends SWIFTSimIO_ tailored to analyses of particles belonging to individual simulated galaxies. It inherits from and extends the functionality of the ``SWIFTDataset``. It understands the output of a halo finder (supported: `Velociraptor`_; planned support: `HBT+`_) and therefore which particles belong to a galaxy, and its integrated properties. The particles occupy a coordinate frame that is enforced to be consistent, such that particles loaded on-the-fly will match e.g. rotations and translations of particles already in memory. Intuitive masking of particle datasets is also enabled. Finally, some utilities to make working in cylindrical and spherical coordinate systems more convenient are also provided.

 Halo finders
 ============
 
-:mod:`swiftgalaxy` uses a helper class to create a uniform interface to outputs from different halo finders. Provided a python library to read the halo finder outputs already exists, this helper class is usually lightweight and easy to create. Currently, the Velociraptor halo finder has built-in support, and support for HBT+ is planned. Other halo finders may be supported on request -- pull requests to the repository are also welcome.

 The second argument to create a :class:`~swiftgalaxy.reader.SWIFTGalaxy` is an instance of a class derived from the base helper class :class:`~swiftgalaxy.halo_finders._HaloFinder`, such as :class:`~swiftgalaxy.halo_finders.Velociraptor`. This object has multiple roles. It will be aware of:
