1 One observation of poor quality was taken on  1911 September 29. Though a
 1  hundred times less weight in comparison to good quality observations was
 1  applied, this measurement was rejected in the process of selection and
 1  weighting.
 2 One observation were taken on 1912 May 09, two in 1912 September 09, but all
 2  three were rejected as wrong; also a single observation from 1912
 2  September 10 was rejected.
 3 Three observations taken on 1913 October 25, 26 and 31 are outliers.
 4 One observation taken on 1914 June 24 (well fitted in right ascension and
 4  declination) and two observations taken on 1915 August 10 (only in
 4  declination) are also used here for orbit determination.
 5 Two observations were taken on 1925 March 22, but were rejected as outliers.
 6 One observation was taken on 1925 April 05 and was included into orbit
 6  determination only in right ascension.
 7 Two observations were taken on 1926 June 09 and 10 and were included into
 7  orbit determination only in right ascension and declination, respectively.
 8 One observation taken on 1933 January 20 was included into orbit
 8  determination in declination.
 9 One observation taken on 1937 November 12 was included in declination into
 9  orbit determination.
10 Three observations were taken on 1941 January 03 - these were included into
10  orbit determination in right ascension only.
11 Two observations were taken on 1943 March 11 and were included.
12 One observation taken on 1946 January 29, was included.
13 Two observations were taken on 1946 August 13; the first was included only
13  in declination, and the second in both coordinates.
