These measurements are to be made in conjunction with the WFPC line_4: measurements of the same check fields. The results of these measurements line_5: are the stability characteristics of the FGS to allow an estimate line_6: of the frequency of OFAD re-calibrations.

(1) The dominant guide star of each pair should line_3: be in FGS#3, and the roll star in FGS#1. (2) If possible, the dominant line_4: guide star should be chosen as close to FGS#2 as feasable (it is line_5: best if in the half of FGS#3 that is closest to FGS#2.)

Any significant changes will indicate the need for a line_4: complete recalibration using AST-SV-02 for that particular FGS. We will line_5: also establish a frequency of recalibration of the FGS geometries. line_6: A non-null result indicates the need for further analysis prior to continuing line_7: the SV program. ! question: 13 section: 1 line_1: This test extends AST-OV-12 desorption measurements to SV.
