- Orbit.vT(*args, **kwargs)[source]¶
Return rotational velocity at time t.
- Parameters:
t (numeric, numpy.ndarray or Quantity, optional) – Time at which to get the rotational velocity. Default is the initial time.
vo (float or Quantity, optional) – Physical scale for velocities in km/s to use to convert. Default is object-wide default.
use_physical (bool, optional) – Use to override object-wide default for using a physical scale for output.
quantity (bool, optional) – If True, return an Astropy Quantity object. Default from configuration file.
- Returns:
