# ConstantRotatingFrame¶

class gala.potential.frame.builtin.ConstantRotatingFrame

Bases: gala.potential.frame.cframe.CFrameBase

Represents a constantly rotating reference frame.

The reference frame rotates with constant angular velocity set by the magnitude of the vector parameter Omega around the axis defined by the unit vector computed from the input frequency vector.

Parameters: Omega : Quantity The frequency vector, which specifies the axis of rotation and the angular velocity of the frame. units : UnitSystem (optional) Set of non-reducable units that specify (at minimum) the length, mass, time, and angle units.
