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 is almost always done after the focus script has run and has returned a value. There are plans to fully integrate the focus script into the LOUI which would make this widget redundant.

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.

???xpix & ypix are the center pixel values and the xsize & ysize are the number of pixels you want for the subframe being created. Then you just have to pick a number for the subframe and make sure to put the correct subframe number in the box on the upper right before taking the image. By default subframe number of 0 is reserved for full size image.
