Many dedicated colleagues have contributed time and expertise to the STScI FGS Astrometry Program over so many years. (and in fact,
were the FGS Astrometry Program). We wish to express our sincerest gratitude for their essential support of this program (in the hope it continues through many more years): Linda Abramowicz-Reed and Kevin Chisolm at BFGoodrich, the members of the Space Telescope Astrometry Team, especially Otto Franz and Larry Wasserman at Lowell Observatory, Fritz Benedict and Barbara McArthur with the University of Texas at Austin, and Denise Taylor at STScI.
STScI would like to thank BFGoodrich, in particular Kevin Chisholm and Linda Abramowicz-Reed for their invaluable assistance during the adjustment of the Articulating Mirror Assembly (AMA) to re-optimize FGS1r (on three occasions), FGS2r, and FGS2r2. And not least, we would like to acknowledge that Chris Ftaclas originated and developed the conceptual basis of the AMA, which has enabled the FGS1r to fulfill its potential as a science instrument.
We would also like to thank Susan Rose and Steve Hulbert at STScI for their invaluable help with the preparation and publication of this Instrument Handbook. Without their patience and guidance, this Handbook could not have come together.
