Bases: ndcube.NDCube

PUNCHCube with a secondary celestial WCS.

celestial_wcs = None#
replace(data: numpy.ndarray | None = None, meta: punchbowl.data.meta.NormalizedMetadata | None = None, wcs: astropy.wcs.WCS | None = None, celestial_wcs: astropy.wcs.WCS | None = None, unit: astropy.units.Unit | None = None, mask: numpy.ndarray | None = None, uncertainty: astropy.nddata.StdDevUncertainty | None = None) → PUNCHCube[source]#

(Shallow) copy this PUNCHCube, but with certain attributes replaced.

Useful because PUNCHCubes don’t allow changing their data array, WCS, etc., so to change the WCS you have to make a new cube. Using this function ensures everything is copied over.

Parameters:

  • data (ndarray | None) – A replacement data array

  • meta (NormalizedMetadata | None) – A replacement meta

  • wcs (WCS | None) – A replacement WCS

  • celestial_wcs (WCS | None) – A replacement celestial WCS

  • unit (Unit | None) – A replacement unit

  • mask (np.ndarray | None) – A replacement mask

  • uncertainty (StdDevUncertainty | None) – A replacement uncertainty

Returns:

cube

Return type:

PUNCHCube
