multicolorfits.reproject_cube

multicolorfits.reproject_cube(mapin, hdrfrom, hdrto, scale=False, method='interp', parallel=True, returnfootprint=False, print_progress=False)

Reproject a 3D cube from one WCS header onto another, plane by plane.

Calls reproject_image() for each spectral (or other non-spatial) slice. For long cubes, set print_progress=True to show a stdout progress bar via draw_progress_bar() (zero dependencies). Scripts that prefer tqdm can loop over planes themselves and call reproject_image — see that helper’s docstring for an example.

Parameters:

• mapin – See reproject_image().

• hdrfrom – See reproject_image().

• hdrto – See reproject_image().

• scale – See reproject_image().

• method – See reproject_image().

• parallel – See reproject_image().

• returnfootprint – See reproject_image().

• print_progress (bool, optional) – If True, update an ANSI progress bar on stdout after each plane (default False).

Returns:

array or (array, array) – Reprojected cube (, optional footprint cube when returnfootprint=True and method='spi').
