FGS1r's Angular Resolution: Conclusions
Figure A2.5 shows that FGS1r detects duplicity at component separations as small as 7 mas, and Table A2.2 shows that this instrument can accurately measure these separations if the magnitude difference is constrained (for projected separations < ~15 mas, no constraints are necessary for larger separations).
Details of the angular resolution test design and results are currently available on the FGS Web site.
