PURPOSE: Verify the following Target Acquisition functions: 1. Obtain and analyze an "Early Acquisition" WF/PC image from prop 1353. 2. Verify the capability to make small offset maneuvers via direct commands to the DF-224. ------------------------------------------------------------------------------------ 3. Description of proposed observations. OBSERVATION: An image of the field containing these stars will be taken as an Early Acq from prop 1353. The image will be used as an "Early Acquisition" observation, from which the relative positions of HD 93204 and HD 93205 will be measured. HD 93205 will be acquired using a Mode II Search and Locate sequence. The star will be centered in the LSA and a brief confirmation spectrum will be obtained with grating G5 (G140L). An image of the field will be obtained with the WF/PC. An offset to the position of HD 93204 will be performed using a DF224 offset. After the maneuver is completed a second WF/PC image will be obtained. These images will be useful for troubleshooting in the event that the offset maneuver is not successful. The Search and Locate phases of target acquisition will be used to center HD 93204 in the LSA, followed by a brief confirmation spectrum. ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. OV-SV Prerequisites: PREREQUISITES: 1. HRS-05.2 Mode II Target Acquisition -- Target Locate (Prop 1352) SV Minimum Plan: all Guiding Tolerance: 0.025 arc seconds ------------------------------------------------------------------------------------ 7. Data reduction and analysis plans. Maps will be analyzed to confirm centering. Spectra analyzed to confirm proper star. We will need to use ST ScI facilities, presumably SDAS to analyze the WF/PC Early Acquisition image to derive the offsets between stars. The results of this analysis will be entered into the SMS for this test - HRS-05.3. ------------------------------------------------------------------------------------ 10.
