\subsubsection{ADSC Two Theta}
The Crystallogic tables used by many ADSC detectors 
such as the Quantum 210
use a geometry for controlling the two-theta angle of the detector
that is not immediately obvious.  
The \textit{adcs\_two\_theta} pseudomotor driver provides a way
controlling the two theta angle via the height motor of the detector
table assembly.

\textbf{Note:}
This driver was written to support a situation where a Quantum 210
detector was being repaired, but the beamline users wanted to continue
to use the detector table with a backup MarCCD detector that they had.
It is not expected that this pseudomotor driver will be useful for
any other situation.
