EllipseBeam.set_moments(sx, sxp, sxxp)[source]¶

Sets the beam moments directly.

Parameters:

Parameters:	sx : float Beam moment where $\text{sx}^2 = \langle x^2 \rangle$ . sxp : float Beam moment where $\text{sxp}^2 = \langle x'^2 \rangle$ . sxxp : float Beam moment where $\text{sxxp} = \langle x x' \rangle$ .

sx : float

Beam moment where $\text{sx}^2 = \langle x^2 \rangle$ .

sxp : float

Beam moment where $\text{sxp}^2 = \langle x'^2 \rangle$ .

sxxp : float

Beam moment where $\text{sxxp} = \langle x x' \rangle$ .
