*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:
<pre>
[tem]
class: tecnai.Tecnai
cs: 2.0e-3
[camera]
class: gatan.Gatan
zplane: 50
</pre>
* Separate computers for the two instruments: configure only the instrument reside on the particular computer
** On the computer that controls the tem:
<pre>
[tem]
class: tecnai.Tecnai
cs: 2.0e-3
</pre>
** On the computer that controls the digital camera:
<pre>
[camera]
class: gatan.Gatan
zplane: 50
</pre>
* 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:
<pre>
[camera1]
class: de.DE12
zplane: 50
[camera2]
class: de.DESurvey
zplane: 50
</pre>
* 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:
<pre>
[camera1]
class: de.DE12
zplane: 50
[camera2]
class: tietz.TietzPXL
zplane: 5
</pre>
* 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.
<pre>
[camera1]
class: dmsem.GatanK2Base
zplane: 50
[camera2]
class: dmsem.GatanOrius
zplane: 49
