III/127 Radial Velocities of Bright Southern Stars (Andersen+ 1983-85) ================================================================================ Radial Velocities of Bright Southern Stars I Andersen J., Nordstroem B. =1983A&AS...52..471A Radial Velocities of Bright Southern Stars II Andersen J., Nordstroem B. =1983A&AS...52..479A Radial Velocities of Bright Southern Stars IV Nordstroem B., Andersen J. =1985A&AS...61...53N ================================================================================ ADC_Keywords: Radial velocities; Stars, bright Description: Radial Velocities of Bright Southern Stars is the result of an effort to determine radial velocities for those southern stars in the "Bright Star Catalogue" with no previously published radial velocity. This version of the catalog combines three lists of data published separately during 1983-85, the first for B-type stars, the second for late-type stars, and the last for A- and F-type stars. J. Andersen notes the following in a 1987 private communication: "In order to make the 1982 edition of the 'Bright Star Catalogue' as complete as possible, preliminary or even incomplete data for many stars in this catalogue were provided in advance of publication. The present catalogue presents the final values, which should supersede (not be averaged with!) those given in the Bright Star Catalogue." The method employed throughout the entire observation program is described by Andersen & Nordstroem (1983A&A...122...23A).

Any secondary components are indicated by a note in file "notes.dat" (see Remarks field) Note (4): this parameter "measures the ratio between the observed plate-to-plate scatter for a given star and the scatter expected for a constant star measured with the same uncertainty". A value of 1.75 is considered the lower limit for possible variability in velocity, and 2.5 the lower limit for certain variability. See Andersen & Nordstroem (1983A&A...122...23A) Note (5): The rotation class has the following values: 0 = v.sin(i) < 15km/s 1 = 15 < v.sin(i) < 50km/s 2 = 50 < v.sin(i) < 100km/s 3 = 100 < v.sin(i) < 175km/s 4 = 175 < v.sin(i) < 250km/s 5 = v.sin(i) > 250km/s Note (6): Remarks are indicated by one or more of the "words": REM = Remark in file "notes.dat" SB2 = Double-line spectroscopic binary (RV2 given in file "obs.dat") SB3 = Triple-line spectroscopic binary (RV3 given in file "obs.dat") VAR = Certain variability VAR? = Possible variability -------------------------------------------------------------------------------- Byte-by-byte Description of file: obs.dat -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1- 6 I6 --- HD HD number of the star 7- 8 A2 --- m_HD [ A-D] HD suffix (for multiples) 10- 21 F12.4 d JD [2442310/2445780] Julian date of observation 22- 25 F4.1 --- w [0.3/1] Weight of the plate 29- 34 F6.1 km/s RV1 Radial velocity of the primary 35- 39 F5.1 km/s e_RV1 [0.1/10] Mean error on RV1 40- 42 I3 --- N1 [2/18] Number of lines measured to determine RV1 46- 51 F6.1 km/s RV2 ?

Andersen) to the CDS in 1984. The 3 catalogs were numbered III/102, III/103, and III/104. The three catalogs were merged into a single one at the Greenbelt Astronomical Data Center (ADC) by Anne C. Raugh in September 1987, and described in the ADC "Documentation for Machine-Readable Version". Full JD observation dates have been inserted in the "obs" file, and this ReadMe documentation was prepared by F. Ochsenbein and J. Lyu in January 1997. The files "ReadMe" and "notes.dat" were revisited in June 2016 at CDS to add the bibcodes (Francois Ochsenbein) ================================================================================ (End) C.-H.
