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

* height and width is 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.

*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.

* 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.
