CylindricalDifferential

class astropy.coordinates.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_rhoQuantity [:ref: ‘speed’]

The differential cylindrical radius.

d_phiQuantity [:ref: ‘angular speed’]

The differential azimuth.

d_zQuantity [:ref: ‘speed’]

The differential height.

copybool, optional

If True (default), arrays will be copied. If False, arrays will be references, though possibly broadcast to ensure matching shapes.
