h3. TEM
*cs is the coefficient of spherical aberration in meters*. Find out from TEM manufacture the proper value for your tem.
For example
<pre>
[tem]
class: tecnai.Tecnai
cs: 2.0e-3
</pre>
h3. Camera
*height and width are number of pixels based on the orientation presented in Leginon image viewer*
* Some Tietz camera may have an odd physical dimension. Use TCL/EMMenu program to find out the good dimension used in Tietz's own software and entered in this configuration.
For example
<pre>
[camera]
class: gatan.Gatan
zplane: 50
height: 4096
width: 4096
</pre>
*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.

*HEIGHT and WIDTH are not shown in these examples for simplicity*
* 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 at the same plane:
** On the computer that controls the digital camera:
{{include(Instrumentcfg_for_DE-12)}}
* 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
