Position-Velocity Slice Extractor
=================================

The concept of the ``pvextractor`` package is simple - given a path defined
in sky coordinates, and a spectral cube, extract a slice of the cube along
that path, and along the spectral axis, producing a position-velocity or
position-frequency slice.

The path can be defined programmatically in pixel or world coordinates, but it
can also be drawn interactively using a simple GUI. We also provide a DS9
analysis plug-in that allows the path to be drawn in DS9, and the resulting
slice shown in a new frame in DS9. Finally, the slicing capability is available in Glue_.
