The focus tests are to attempt to determine if our current "best focus" is truly the "best focus". Evidence suggests we are fairly close.
4 1 Kevin Reil
5 1 Kevin Reil
The test will consist of moving the focus set point to +25 microns for 10 exposures, -25 microns for 10 exposures and back to 0 microns for 10 exposures. This is done by issuing the following command via the Architect Console

<pre> FOCUS.AOS set set_point 0,0,25,0,0,0 </pre>
8 1 Kevin Reil
take 10 exposures
