Catalogues and Data References, (abbreviated IDS), by H. M. Jeffers, W. H. van den Bos, and F. M. Greeby, Publ. Lick Obs., Vol. 21, Pts. I and II. This index is a complete list of doubles catalogued to 1960 (thus including many optical doubles), without quoting individual observations. Pairs discovered later are recorded in a card file at the U.S. Navy Observatory.

Magnitudes of Double-Star Components,Next to the relative positions, for which a variety of measuring methods was on the agenda, the photometric data on double stars are another piece of data not easy to get. Let mA and mB be the apparent magnitudes of the components and mt the total (combined) magnitude of the pair. By definition, . . >0. The formula

Ephemeris Formulae,For any time ., the coordinates ., . or ., . are computed from the elements by means of the following formulae:.The process leads from the mean anomaly . via the auxiliary angle . (the eccentric anomaly) to the polar coordinates (. = true anomaly, . = radius vector) or to the normalized rectangular coordinates . in the true orbit (Figure 8).

Micrometric Observation,nchanged, device — perhaps a unique case in physical science. The older history of micrometer types has been comprehensively described by Becker (1899), and the present section mentions only the two surviving types.
