Functions

extract_pv_slice(cube, path[, wcs, spacing, ...])

Given a position-position-velocity cube with dimensions (nv, ny, nx), and a path, extract a position-velocity slice.

paths_from_regfile(regfile)

Given a ds9 region file, extract pv diagrams for each:

slice_wcs(wcs, spatial_scale)

Slice a WCS header for a spectral cube to a Position-Velocity WCS, with ctype "OFFSET" for the spatial offset direction

Classes

Path(xy_or_coords[, width])

A curved path that may have a non-zero width and is used to extract slices from cubes.

PathFromCenter(center[, length, angle, ...])

A simple path defined by a center, length, and position angle.
