| | 1 | * This is the basic procedure of closing the focus loop. |
| | 2 | |
| | 3 | * Start the DMI pipeline with cycle time of 10 seconds (This should already be |
| | 4 | running if you are on trajectory). |
| | 5 | * Start the DMI metrology loop (this will set the DMI focus point). |
| | 6 | NOTE: The DMI focus point is the distance where the focus will be held if you |
| | 7 | activate the DMI metrology loop. |
| | 8 | * RA will center a star on OWFS1 or OWFS2. |
| | 9 | * Null out tip/tilt offsets on the OWFS camera of choice. |
| | 10 | * Check that the X and Y offsets are nulled if not have the camera re-centered. |
| | 11 | * Start and activate the metrology loop on the OWFS camera of choice. |
| | 12 | NOTE: By activating the metrology loop on the OWFS camera you are not guiding |
| | 13 | focus. This also continuously adjusts the DMI set point. |
| | 14 | * At the end of the trajectory or when cancelling a trajectory all guiding loops |
| | 15 | will be stopped but the DMI focus set point will still remain until you either |
| | 16 | set it manually or close the focus loop on an OWFS camera. |
