RadialDifferential

class astropy.coordinates.RadialDifferential(*args, **kwargs)[source] [edit on github]

Bases: astropy.coordinates.BaseDifferential

Differential(s) of radial distances.

Parameters:

d_distance : Quantity

The differential distance.

copy : bool, optional

If True (default), arrays will be copied rather than referenced.

Attributes Summary

attr_classes
d_distance Component ‘d_distance’ of the Differential.

Methods Summary

from_cartesian(other, base)
from_representation(representation[, base])
to_cartesian(base) Convert the differential to 3D rectangular cartesian coordinates.

attr_classes = OrderedDict([('d_distance', <class 'astropy.units.quantity.Quantity'>)])
d_distance

Component ‘d_distance’ of the Differential.

Methods Documentation

classmethod from_cartesian(other, base)[source] [edit on github]
classmethod from_representation(representation, base=None)[source] [edit on github]
to_cartesian(base)[source] [edit on github]

Convert the differential to 3D rectangular cartesian coordinates.

Parameters:

base : instance of self.base_representation

The points for which the differentials are to be converted: each of the components is multiplied by its unit vectors and scale factors.
Returns:

This object as a CartesianDifferential
