# comp_flower_arc (method)¶

comp_flower_arc(alpha, Rarc, Rext)[source]

Compute the angle and end of a “flower arc”.

Parameters
• alpha (float) – Angular width of the arc (angle(z_top_feft)=alpha/2)

• Rarc (float) – The radius of the arc to draw [m]

• Rext (float) – The radius of the external arc ((Rext,0) is on the flower arc) [m]

Returns

(alpha_lim,z_top_left,z_top_right) – alpha_lim: angle of the arc [ard] z_top_left: first point of the arc z_top_right: second point fo the arc

Return type

(float, complex, complex)
