Pointing Control System mode: Fine Guide, Coarse, None, Track, Moving. For COARSE Visit is executed under fixed head star tracker control. For FINEGUIDE the fixed target visit is executed using guide stars in fine guiding mode. For TRACK the fixed target visit is to be executed using guide stars but not using fine guiding mode. This mode is intended to be used when the telescope focus is not optimal, during commissioning or special engineering tests. For MOVING the moving target visit is to be executed by tracking using guide stars. NONE indicates that the visit does not need to be pointed. It will be used for special visits, such as for loading on-board scripts or other non-standard internal activities.
