Qualifying the set of light spots includes, for each light spot: calculating a first calculated location of the light spot using a first calculation algorithm calculating a second calculated location of the light spot using a second calculation algorithm and when a difference between the first and second calculated locations for the light spot is greater than an agreement threshold, excluding the light spot from the set of light spots and/or from being employed in determining the wavefront of the received light beam.
