concatenate

astropy.coordinates.concatenate(coords)

Deprecated since version 7.2: The concatenate function will be deprecated in a future version. Use np.concatenate instead.

Combine multiple coordinate objects into a single SkyCoord.

“Coordinate objects” here mean frame objects with data, SkyCoord, or representation objects. Currently, they must all be in the same frame, but in a future version this may be relaxed to allow inhomogeneous sequences of objects.

Parameters:

coordspython:sequence of astropy:coordinate-like

The objects to concatenate

Returns:

cskycoordSkyCoord

A single sky coordinate with its data set to the concatenation of all the elements in coords

Notes

As of astropy 7.2, it is possible to combine coordinates with numpy.concatenate, and that is now the recommended way to do it. This function differs from numpy.concatenate in that (i) it does not take an axis argument; (ii) scalar coordinates are allowed to be concatenated with other scalar or one-dimensional ones; (iii) all |SkyCoord| must have the same representation type and either all have or all not have velocities; and (iv) non-frame attributes are removed instead of copied from the first |SkyCoord|.
