Hi everybody,

I am confused here why 
delta=(E_A[-1] - Eg_i)+det?
E_X here =[-11.88936397, -2.7012162 , 2.9208718 , 5.92133842] E_A here =[-0.43373496, 0.14457832] This maybe causes the wrong sign of delta because E_A can be less than E_X?
And by the way why E_A < E_X??

def
six_beam_CaF_MOT(s, det): laserBeams = pylcp.laserBeams() for ii, Eg_i in enumerate(E_X): if ii<3: laserBeams += pylcp.conventional3DMOTBeams( s=s, delta=(E_A[-1] - Eg_i)+det, pol=+1, beam_type=pylcp.infinitePlaneWaveBeam ) else: laserBeams += pylcp.conventional3DMOTBeams( s=s, delta=(E_A[-1] - Eg_i)+det, pol=-1, beam_type=pylcp.infinitePlaneWaveBeam ) return laserBeams
