discov_num notes refcode
STT 337 Quadrant uncertain. Star approaching periastron. Baz1954a
In AJ 63, 68, 1958 I have given a mean of 5 measures of ADS 10828. The B__1958
first measure is not of this pair, but of the nearby pair ADS 10846.
The result for 10828 should read: 1957.449, 22.7, 0.24, 8.4-8.7, n=3 B__1962a
A premature orbit has been computed.
