     ----------
     atommag : float/list of float/None
         Atom magnetic moment.
     angle1 : float/None
         value of angle1.
     angle2 : float/None

     ABACUS support defining mag, angle1, angle2 at the same time.
     angle1 is the angle between z-axis and real spin (in degrees).
-    angle2 is the angle between x-axis and real spin projection in xy-plane (in degrees). 
+    angle2 is the angle between x-axis and real spin projection in xy-plane (in degrees).
     If only mag is defined, then transfer it to magmom directly.
     And if mag, angle1, angle2 are defined, then mag is only the norm of magmom, and the direction is defined by angle1 and angle2.
