The AOS focus command is an accordion UI element (collapsible content) which allows the observer to send a focus offset command to the AOS. This can be used after the focus script has run and one does not agree with the value that is automatically sent. It can also be used to set the general focus offset of 750 microns while in OPEN, OPEN or to correct the offset if the filter wheel gets lost.

Info

If a filter wheel move fails, the code loses track of the relative AOS focus offsets and one should reset the value. So the procedure is to go back to the same filter configuration that the focus script was run and re-send the value obtained from the script using this element. Homing the filter wheels will NOT set the proper focus value in such a case.
