The mirror field is sized according to the receiver height (constant for all receivers), as the center of the field is at
a distance that creates an angle of approximately 60° with the receivers due to the symmetry of the field and a fixed
field aspect ratio. A receiver height (H) of 6.0m is chosen and the width of the mirror field established
D H 2 tan 60 . The start points of the parabolas represent the limits of the mirror field domain and the end points
of the parabola represent the transition point from a single target mirror field to a multiple target field. The
governing equation for the parabolic sections is derived from the equation for the focal point of a parabola:
