Abstract:
New orbital elements are presented for 37 close visual systems that
have been observed and in some cases discovered by speckle
interferometry. Periods of these systems range from 5.7 to 425yr,
semimajor axes from 0.06" to 1.1". Four of these systems (Kui 18, Fin
325, StF 2597, and McA 77) had no previously published orbital
analyses, while elements for a number of other systems have undergone
major revisions. Finally, 135 new or revised interferometric
measurements of these systems are also presented, as well as 8
negative results.

Note on WDS:
WDS designation (epoch-2000 coordinates, in the manner of the
Washington Double Star Catalogue I/107 .
Note on Tel:
The aperture sizes uniquely define the telescope used, as either
the Cerro Tololo 4.0m, Kitt Peak 3.8m, Canada-France-Hawaii 3.6m,
or Mount Wilson 2.5m telescope.
Note on Notes:
1 = Re-reduction of archival data; secondary peak was originally
either undetected or found too weak for reliable
measurement.
2 = Re-reduction of an observation originally published by
Hartkopf et al. (1994AJ....108.2299H 1994AJ....108.2299H)
3 = Re-analysis of the data originally published by McAlister et al.
(1990AJ.....99..965M 1990AJ.....99..965M) found that the secondary peak was
actually too close for reliable measurement.
4 = Previously unpublished negative result.
