+40 12May be B7 II.
+39 472May be cA.
+39 552ADS 14314AB. The published delta m (Aitken, A New General Catalogue
+39 552of Double Stars Within 120 deg of the North Pole) is so large that
+39 552the observed spectrum must actually be entirely that of the primary.
+39 552The primary is said to be composite in the Henry Draper Catalogue,
+39 552and for this reason the star is given two HD numbers, HD 198287/8.
+39 552The spectrum does not appear composite on our plates, and was charac-
+39 552terized by Hynek (Perkins Contribution 1, No. 10, 1938) as one simu-
+39 552lating compositeness because of high luminosity. This conclusion is
+39 552almost certainly correct.
+38 172May be B6 Ia.
+38 832May be B7 Ib.
+37 352May be B8 II.
+37 722May be B7 Ir.
+36 82May be B7 II.

+35 732May be cA.
+34 122May be B8 Ib.
+32 152ADS 13335A.
+31 12H-beta in emission.
+31 152The type given here is purely descriptive; among the grounds for
+31 152doubting it is the fact that the spectrum shows no reddening despite
+31 152its low Galactic latitude. On the plate covering its position, an
+31 152absorption feature which may be H-gamma is strong, while all other
+31 152features, including the Balmer discontinuity, are at the limit of
+31 152visiblity.
+30 172May be B7 II.

+08 86Probably not a true Wolf-Rayet, since Hiltner (Ap.J. Suppl. 2, No. 24,
+08 861956) refers to this star merely as showing high-excitation emission
+08 86superposed on about an O9 spectrum.
+08 116K-line present.

+02 136lished spectral type of B0 III:p pertains to the combined light of the
+02 136system.

+00 16AGK2 asumes Aitken's position angle for AC is 180 degrees in error and

-11 204Of?
