This test will be run following the installation of a flight software change which will position the filter wheels more accurately. It incorporates an ACS anneal and will substitute for one of the routine anneals that are carried out every four weeks. A series of internal flats will be taken with several filters. The exposures will be just long enough to obtain engineering data concerning the wheel positions. One external earth flat will also be taken to provide visual confirmation that the filter is correctly aligned. In the event of a problem being found, an operations request will be issued to revert to the original software. There are several requirements affecting timing and real-time contact. 1. Visit 1 must be scheduled to start within 12 hours of an SMS boundary. 2. Engineering telemetry contact must be available during visits 4, 5 and 6 3. An uplink opportunity must be available, at least 30 minutes after execution of the test, i.e. completion of visits 4, 5 and 6 {visit 7 should have several orbit gap from the last of 4, 5 and 6. 4. Visit 7 may not proceed, nor may any other ACS observation take place after the start of visit 1 until the uplink opportunity has occurred.
