SEPARATED FRINGE PACKET OBSERVATIONS WITH THE CHARA ARRAY. I. METHODS AND NEW ORBITS FOR Delta y DRACONIS, HD 184467, AND HD 198084

We present the modification of the orbits of Delta *y Draconis and HD 184467, and a completely new orbit for HD 198084, including data taken at the Center for High Angular Resolution Astronomy (CHARA) Array. These data were obtained using a modification of the technique of separated fringe packets (SFPs). The accuracy of the SFP data surpasses that of data taken by speckle, but the technique is much more time and labor intensive. Additionally, using SFPs with the CHARA Array, it is possible to obtain separations below the detection range of speckle interferometry (>=30 mas) above the range in 'classic' long-baseline interferometry where fringes from a binary overlap are no longer separated (
