cs is the coefficient of spherical aberration in meters. Find out from TEM manufacture the proper value for your tem.

zplane is a number that gives the order of camera. If a camera with low zplane value is going to acquire an image, Leginon will attempt to retract all cameras at higher zplane values.

  • One computer for both tem and digital camera:
    [tem]
    class: tecnai.Tecnai
    cs: 2.0e-3
    [camera]
    class: gatan.Gatan
    zplane: 50
    
  • Separate computers for the two instruments: configure only the instrument reside on the particular computer
    • On the computer that controls the tem:
      [tem]
      class: tecnai.Tecnai
      cs: 2.0e-3
      
    • On the computer that controls the digital camera:
      [camera]
      class: gatan.Gatan
      zplane: 50
      
  • Two camera that retract/insert at the same time, typically one of them is an off-axis camera, such as in the case of DE12 and DE Survey camera pair.
    • On the computer that controls the digital camera:
      [camera1]
      class: de.DE12
      zplane: 50
      [camera2]
      class: de.DESurvey
      zplane: 50
      
  • Two camera on the same computer but one is retractable and one is non-retractable and at lower position.
    • On the computer that controls the digital camera:
      [camera1]
      class: de.DE12
      zplane: 50
      [camera2]
      class: tietz.TietzPXL
      zplane: 5
      
  • Gatan Orius camera that is installed typically with Gatan K2/Falcon camera is technically on the same plane but is not capable of insertion unless K2 is retracted. On the other hand, K2 camera insertion includes a retraction of Orius at lower level of the function call in DM. Therefore, Orius is considered as a camera at lower zplane.
    [camera1]
    class: dmsem.GatanK2Base
    zplane: 50
    [camera2]
    class: dmsem.GatanOrius
    zplane: 49
