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.

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. |

The built-in offset command in the TCS is absolute and has three modes; TPLANE, SIMPLE, and PA. The tooltips on the labels show the appropriate units for each parameter. The relative offset command is a LOUI implementation by issuing an absorb command immediately after the offset command. It is advisable not to use the relative offset as it is unsupported for cases such as guided offsets.
Sending the clear command is equivalent to sending 0,0 as the parameters and the absorb command causes the pointing center to change to the current location and clears the current offsets in the TCS.
The hand paddle allows one to send incremental offsets for each of the three modes. Pressing one of the hand paddle buttons will increment the current offset parameter and send it immediately to the TCS. The hand paddle only works with absolute offsets.
The tooltips on the labels show the appropriate units for each parameter. The hand paddle text also shows the relevant units for each mode.
