CylindricalDifferential
(d_rho, d_phi=None, d_z=None, copy=False)[source]¶ Bases:
astropy.coordinates.BaseDifferential
Differential(s) of points in cylindrical coordinates.
- Parameters
- d_rho
Quantity
[:ref: ‘speed’] The differential cylindrical radius.
- d_phi
Quantity
[:ref: ‘angular speed’] The differential azimuth.
- d_z
Quantity
[:ref: ‘speed’] The differential height.
- copybool, optional
If
True
(default), arrays will be copied. IfFalse
, arrays will be references, though possibly broadcast to ensure matching shapes.
- d_rho
