Note (1): Indication of the probability that the star belongs to the considered category: '/' denotes a star improperly considered Ap or Am '?' doubtful nature '*' well-known Ap or Am star ' ' other cases Note (2): Running number (initially in tens), ordered by HD number (extension excluded) when such a number exists; stars without HD number (including HDE stars) were merged according to 1900 right ascension truncated to 0.1min. Note (3): Bertaud's catalogue published in "Journal des Observateurs" (1959JO.....42...45B, 1960JO.....43..129B, 1965JO.....48..211B) Note (4): the multiplicity letter identifies the component in the case of double or multiple system where components have not a distinct number, except when the luminosity of the other components is negligible. Note (5): the following conventions are used: Greek letters are coded as *AA, an asterisk followed by two letters: *AL=alpha *IO=iota *RH=rho *BE=beta *KA=kappa *SI=sigma *GA=gamma *LA=lambda *TA=tau *DE=delta *MU=mu *UP=upsilon *EP=epsilon *NU=nu *PH=phi *DZ=dzeta *XI=xi *KH=chi *ET=eta *OI=omicron *PS=psi *TH=theta *PI=pi *OE=omega Latin letters should be considered as lowercase letters. Note (6): for close double stars, this magnitude was corrected from the companion's luminosity. Note (7): for close double stars, the colour index refers to the combined light. Note (8): A dash in column 112 indicates an Am star; this dash separates the spectral type deduced from the K line and the spectral type deduced from the metallic lines; delta Del-type stars are classified as Am, and marked with DD. Another character in column 112 means an Ap star, and the spectrum is followed by the symbols of the elements with abnormal abundances. "HE FBL." means "He-weak" See also the "*" note (column 122) Note (9): the symbols used in columns 122-132 have the following meaning: '*' = Note or remark of various nature, e.g. about the spectrum. 'N' = Other designations (see also notes A, D, V) B for number in B. Boss's "Preliminary General Catalogue"; W for number in Wilson's General Cat. of Stellar Radial Velocities III/21; Second DM number 'D' = Note concerning duplicity: ADS (Aitken's catalogue) designation, magnitude and angular distance of the companion 'A' = Note concerning clustering: cluster, group or association to which the star belongs, at least optically; star identification number(s) in the cluster or association 'V' = Note about variability: variable name; nature of the variability, if known, when it is not of the alpha CVn type. 'P' = Note about the known or proposed period observed for the variations of: - the luminosity and/or colours (L) - the magnetic field (M) - the intensity of spectral lines (S) - the radial velocity computed from peculiar element lines. (V) 'B' = Note about binarity: V.R.V. stands for Variable Radial Velocity P provides the period of Spectrocopic Binaries, and E the eccentricity 'H' = Note about magnetic field: extreme values measured for the effective magnetic field (defined in Babcock, =1957ApJS....3..141B) followed by the number of measurements within brackets 'R' = Note concerning the rotational velocity; value of the projected equatorial velocity (v sin i) 'S' = Remarks concerning Stroemgren's Photometry uvbyH-beta 'C' = Note about detection criteria, when the p or m feature is not confirmed with classical spectroscopy. Used abbreviations: UV = ultraviolet spectrophotometry (satellite obs.) GEN = Geneva 7-colour photometry MTZ = H.M. Maintzen's photometry GCPD/75 (1976A&A....51..223M)
