B.3 FGS1r’s Angular Resolution: Conclusions

Figure B.5 shows that FGS1r detects duplicity at component separations as small as 7 mas, and Table B.1 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 page.
