Abstract:
Results of our second observational run of binary star interferometric
measurements with an ICCD speckle camera attached to the 1.52m
telescope of the Observatorio Astronomico Nacional at Calar Alto
(Almeria, Spain) in 2000 June-July are presented. The measured angular
separations range from 0.096" to 6.558". With the use of the new
speckle data, the orbits of the visual binaries WDS 14369+4813 and
WDS 21597+4908 are improved.

(Mason, Wycoff, & Hartkopf, 2003, Cat. I/281).
Note (2): The observations have routinely been performed by using a
520/24nm filter except those made with red filter 660/40nm
denoted "R" in the column.
