Actuator = Actuator(*,3)

Unfortunately, this result in a 2-D array with a trailing dimension of
1, which gets automatically converted by IDL into a 1-D array. I don't

Actuator = [ [fltarr(100,3)], [Actuator], [floatarr(100,3)] ]

Actuator = [ [Actuator(*,0:1)], [fltarr(100,1)], [Actuator(*,2:3)] ]
