Leginon

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
  height: 4096
  width: 4096
  

• 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
    height: 4096
    width: 4096
    

• Two cameras 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
    height: 3072
    width: 4096
    [camera2]
    class: de.DESurvey
    zplane: 50
    height: 2048
    width: 2048
    

• Two cameras 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
    height: 3072
    width: 4096
    
    [camera2]
    class: tietz.TietzPXL
    zplane: 5
    height: 4096
    width: 4096
    

• 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.
