Hartkopf et al., 1993, AJ, 106, 352

Notes to Table 1

00283-2020 = B 1909: This has long been a difficult visual system, with the two
             components remaining within 0.2 arcsec of each other throughout the
             orbit. With this observation we have completed a full revolution
             using speckle data alone, and have derived new orbital elements
             which will be published shortly.

00479-2921 = I 261: Having had only one other measure in the last 35 years, this
             pair needs further observation, especially since we appear to be
             near periastron at this epoch.

01243-0655 = Bu 1163: A new interferometric orbit of this very eccentric (e =
             0.94) system is in preparation.

02396-1153 = Fin 312: Residuals from the orbit of Hartkopf et al. (1989, AJ, 98,
             1014) are (0.2 deg, -0.003 arcsec).

02398+0009 = A 1928: Periastron passage for this very close visual pair has thus
             far been well covered by speckle.

02518-2117 = See 21: This very close visual system was discovered at a
             separation of 0.36 arcsec and has closed steadily for over 90
             years. It is unknown at this point whether the system is still
             approaching periastron or has begun to widen.

03544-4021 = Fin 344 AB: This is the first observation of this system since
             those of Finsen in the 1960's, and is considerably closer than any
             of his results. It is known that in some instances Finsen's rho
             values appeared systematically larger than those of speckle;
             further observations of this system will determine whether such is
             again the case.

04037-1545 = A 2913: This system closed steadily from its discovery at 0.45
             arcsec in 1915 to 0.22 arcsec in 1959; this is the first
             observation in 30 years so it is unknown whether the pair has
             passed through periastron.

04256+1557 = Fin 342 Aa: Residuals from the orbit of McAlister et al. (1988, AJ,
             96, 1431) are (-2.3 deg, 0.008 arcsec).

05248-5219 = I 345 AB: This system has also decreased in separation steadily
             since the 1920's, and was last resolved visually in 1983.

05565-2631 = B 94: This system was last resolved visually in 1978, and appears
             to be continuing to approach periastron.

07003-2207 = Fin 334 Aa: The system has opened slightly since the last speckle
             observation in 1989.3; unfortunately it was last observed in 1966
             so it may be difficult to pin down the time of periastron passage.

08125-4616 = CHARA 143 Aa: These measurements confirm the discovery observation
             of this close companion to See 96, made in the spring of 1989.

08285-0230 = A 551 AB: Speckle observations are in poor agreement with the orbit
             of van den Bos (1953, Union Obs. Circ., 6, 211). A new orbit is in
             preparation.

09123+1459 = Fin 347 Aa: Residuals from the orbit of Hartkopf et al. (1989, AJ,
             98, 1014) are (-0.3 deg, -0.003 arcsec) and (-3.2 deg, 000.003
             arcsec).

10120-2836 = B 194: Periastron passage apparently occurred about the time of or
             shortly before our first speckle observation in 1989.3.

12597-0348 = CHARA 39 Aa: This interferometric system has now completed nearly
             180 deg of revolution since its discovery in 1984. A preliminary
             determination of orbital elements yields a low-eccentricity orbit
             with a period of 15.7 years. Absolute quadrant determinations based
             on reanalysis of earlier speckle data have ruled out a possible
             short-period high-eccentricity orbit. A more complete orbital
             analysis is in progress.

14373+0217 = CHARA 42 Aa: This system apparently is continuing to close toward
             periastron.

16057-0617 = Fin 384 Aa: Residuals from the orbit of Baize (1992, A&AS, 92, 31)
             are (-4.5 deg, 0.003 arcsec).

16245-3734 = B 868: This system may have made a very close periastron passage
             between the times of our 1989.3 observation (rho = 0.039 arcsec)
             and this one, although unfortunately the system was not observed in
             1990.

16391-3713 = Fin 340 AB: From its discovery in 1954 through the mid-1960's, this
             system closed from 0.14 arcsec to 0.10 arcsec and increased in
             theta from 147 deg to 172 deg. It is impossible to determine from
             this single speckle measure whether the pair has gone through
             periastron and flipped quadrant, but this should become obvious
             within the next couple of observations.

16438-5330 = Fin 251 AB: The close third component CHARA 147 Aa discovered in
             1989.3 was unfortunately not confirmed in these observations.

17207-5625 = Fin 255 AB: This observation finally confirms the discovery of this
             system by Finsen, made in 1931!

19253-2431 = Fin 327: With 15 years of speckle data on this system we are
             finally able to attempt to improve upon Finsen's (1965, Republic
             Obc. Circ., 7, 85) orbital elements. We apparently view the pair at
             a nearly 90 deg inclination and since the Delta(m) for the
             components is near zero there is considerable ambiguity between a
             high-eccentricity short-period orbit and a low-eccentricity
             long-period one. A new orbital analysis is now in preparation,
             including reanalysis of earlier speckle data in order to derive
             absolute quadrants and possibly resolve this ambiguity.
