V/103                  NGP G5-M stars RV, DDO and BV photometry   (Yoss+, 1997)

Radial velocities and DDO, BV photometry of Henry Draper G5-M stars near the North Galactic Pole Yoss K.M., Griffin R.F. <J. Astrophys. Astron., 18, 161 (1997)> =1997JApA...18..161Y
ADC_Keywords: Galactic pole, north ; Radial velocities ; Photometry, DDO ; Photometry, UBV ; Space velocities ; Abundances, [Fe/H] ; Proper motions ; MK spectral classification Keywords: North Galactic Pole - radial velocities - BV and DDO photometry - spaces velocities - abundances - Galactic structure Abstract: Radial velocities are given for some 900 stars within 15° of the North Galactic Pole, including almost all such stars classified G5 or latter in the Henry-Draper Catalogue (Cat. III/135). Luminosities, two-dimensional spectral classes, composition indices, and distances are derived for the majority of the sample through DDO and BV photometry. The radial velocities come from several instruments (see the "Note(2)"(?) section below) ; the BV and DDO photometries were obtained at Mount Laguna Observatory, with the San Diego State University 24-inch Schmidt reflector.

Note (2): the source of the proper motion is indicated as: a: Astrographic Catalogue of Reference Stars (Cat. I/171) i: Hipparcos Input Catalogue (Cat. I/196) Note (3): the source is the radial velocity is indicated as: p: gamma-velocity from published data by Griffin g: gamma-velocity from preliminary unpublished orbit by Griffin P: gamma-velocity from published data by others nd: no observable or measurable dip st: radial-velocity standard Note (4): The spectral types are one-dimensional spectral types from the HD catalogue, or two-dimensional types gathered from various sources, in particular: *: BSC (Cat. V/50) two-dimensional class h: Heard (1956PDDO....2..105H) two-dimensional class u: Upgren (1962AJ.....67...37U, Cat. III/10) two-dimensional class if a two-dimensional type published later is not available Note (5): possible candidates for Galactic halo or thick-disk giants from Δ4548 process analysis are marked by a 'D'. Note (6): Colour excess, which in this case, since there is virtually no interstellar reddening, represents the natural spread in (B-V) for a given MK class, plus any error in the DDO MK class.

Upgren merely comments "Double star", without saying whether his identifier belongs to both stars or only to one or the other.
