The accuracy line_15: goal of this dedicated test is 50 mas for SI/WFPC2 calibration. ! question: 3 section: 1 line_1: Test Description: line_4: For the SI portion of the test, each SI will acquire line_5: a nearby astrometric cluster star and (for the aperture SIs only) line_6: will center it in the target acquisition aperture using onboard line_7: TA procedures. Immediately following the acquisition and without line_8: moving the telescope, the WFPC2 will take an image of the line_9: cluster stars in its field of view. This pair of activities line_10: will be repeated for each SI in turn. The same pair of line_11: guides stars and roll angle will be used throughout the SI line_12: portion of the test thus eliminating systematic errors. line_13: Only small angle manuevers will adjust the vehicle for each line_14: SI sequence. ! question: 3 section: 3 line_1: The FGS portion of the test will consist of 2 POS line_2: MODE Observations of cluster stars in FGS2. question: 4 section: 1 line_1: This is an HST alignment diagnostic test and falls under the line_2: category of Engineering/Observatory level test. ! question: 5 section: 1 line_1: **SPECIAL REQUIREMENTS: THIS TEST CALLS FOR NON-STANDARD line_2: COMMANDING AND SCHEDULING: line_4: 1.

Each SI aperture addressed in the line_5: test will be expressed in a WFC2 coordinate frame in arcsec.
