Table: Meaning of Note Codes
Code Volume Meaning
N All A note exists for this star in File 2.
G All This star is in the General Catalogue (GC) (Boss 1937).
C All Catalogue: A change has been made to this record. If a component letter has been entered for a pair of stars with the same DM number, which is not in the Washington Double Star Catalog, no additional information is provided. All other changes are listed in Table [*].

Notes: Information not provided in the original note has been added. ``Not in the WDS'' is always an addition but is not marked.


A All The star is in the New General Catalogue of Double Stars (Aitkin 1932) (ADS), but the number is not given in the notes.
m 13 The spectral type has been determined by Miss Cannon.
m 14 The spectral type was determined by Mrs. Mayall.
g 17 The spectral type was determined by Dr. Goedicke.
v 18,19,20,21,22 The spectrum and magnitudes are from the Leander McCormick Observatory.
a 24 The star is in the appendix of the Cambridge AG Catalog, page 299.
c 24 The star is not in the Cambridge AG Catalog but was added to fill sparse regions.
e 24 The position from the Greenwich 1910 Catalogue was not used.
r 24 The star is not in the Greenwich 1910 Catalogue.
: 24 The star is not in the Second Catalogue of the Astronomischen Gesellschaft (AG2). The positions are derived from the Trans. Astron. Obs. Yale Univ. 9 but reduced to the FK3 system.
c 25 The star is not in the Berlin B Catalog but was added to help fill sparse regions. No proper motions are given for these stars. The magnitude is from the BD.
* 25 The proper motion is derived from the mean of the positions in Trans. Astron. Obs. Yale Univ. 10 and the AG2.
Y 25 The star is not in the AG2; the proper motions are from Yale only.
* 261 The proper motion depends only on the Yale position and the position for the epoch 1930.
Q 28, 29, 30 Only a single plate was measured.
Y 28, 29, 30 The proper motion is based on Yale only.
H 30 The star is in both the GC and in Luyten's Bruce Proper Motion Survey (1938-1941).
L 30 The star is in the Bruce Proper Motion Survey.
R 30 The star was used as a reference star.
S 30 The star is in the GC and was used as a reference star.
T 30 The star is in the Bruce Proper Motion Survey and the GC and was used as a reference star.
U 30 The star is in Luyten's Bruce Proper Motion Survey and was used as a reference star.
M 31 More than one Melbourne Catalogue was used for proper motion reduction.
P 31 The indicated large proper motion has not been confirmed in a search of other proper motion catalogues.
M 322 A visual magnitude is not present in the Cape Photographic Catalogue (CPC) (Jackson and Stoy 1954-1958); it has been derived from the photographic magnitude and the color index. If both the magnitude and the color index are missing, the visual magnitude was constructed from the photographic magnitude and the spectral type.
