V/36B       Supplement to the Bright Star Catalogue     (Hoffleit+ 1983)

A Supplement to the Bright Star Catalogue Hoffleit, D., Saladyga, M., and Wlasuk, P. <Yale University Obs. (1983)> =1982BS....C......0H
ADC_Keywords: Combined data ; Stars, bright Description: The catalog is an extension of the BSC4 (Hoffleit 1982; see catalog V/50) and contains compiled data on stars for which photoelectric determinations are given as 7.10V or brighter and that are not already included in the latter catalog. The data included in the supplement are basically the same as those in the BSC4 itself, and the format of the machine version is very similar. Notable differences are that the NAME column has been omitted, since very few supplement stars have Bayer or Flamsteed designations, and has been replaced with the SAO number. Also, the parallax field includes only data determined from trigonometric methods; all dynamical parallax data have been relegated to the REMARKS. Position-angle data are given in the main table for double stars, whereas they were contained, if reported, only in the REMARKS file of the BSC4. Remarks for supplement stars are given in a separate file of the machine version and are present for 49% of the stars. The introductory file "intro.doc" contains the text given in the introduction to the published catalog except that the figures are, of course, not included. Data included in the catalog "bsc4s.dat" are HD number; DM number; SAO number; double-star code or identification; variable-star identification; right ascension (B1900) declination, right ascension (B2000) declination; galactic coordinates; V magnitude; B-V, U-B, R-I colors; spectral type; annual proper motions; parallax; radial velocity (km/s): and projected rotational velocity v sin i (km/s). Data included for multiple stars are magnitude difference, separation (arcsec), position angle (PA) of components, component identifications (A, B, ...), and number of components (N). A remarks flag is included as a pointer to a remarks file. The third file "remarks.dat" contains the actual remarks for stars flagged in the data file. File Summary:

Note on m_HD: used for multiple systems, or /X when more than a single HD star is included, e.g. HD 17245/6. NOTE: m_HD is "S" for the 3 stars not in HD catalogue, for which the SAO number is listed in column HD; those stars are SAO 250043 (CP-60 980), SAO 179278 (BD-20 3283) and SAO 252421 (CP-61 3926) Note on ADS: spectroscopic and eclipsing binaries are not considered here. The field is uniform with the catalog codes in byte 28, ADS numbers in bytes 29-33, and multiple-star letter designations for components of a system which the HD number represents in bytes 34-35. Other designations include: W Worley (1978; see Worley 1982) update of the IDS (Jeffers et al. 1963) (see catalog I/237) C Couteau 1978 (see catalog I/209) D Duplicity discovered by occultation Note on Vname: these designations include: (a) constellation designations from the General Catalogue of Variable Stars (see 4th Edition as Catalog II/139) (b) numbers (alone) from the New Catalogue of Suspected Variable (see latest version in Catalog II/140) (c) Var and Var? for unnamed variables and suspected unconfirmed variables not included in the General and Suspected catalogs. Can apply to the HD number and/or a close companion. Note: HD 139216 = Tau4 Ser is recorded as "@t|4 Ser" where the character following the t is a vertical bar. Note on Vmag: Magnitudes of variables and/or binaries may be reported to 0.1 mag only. Note on n_R-I: this code may be a colon indicating a larger uncertainty, or (blank) - on Johnson system; E - mainly from Eggen, on Kron system; C - from Cousins, close to Kron system (the Johnson and Kron filters have different passbands and may not be used interchangeably). Note on SpType: If the complete modern (MK) classification is too long for the data field, it is given in the remarks file and an asterisk (*) occurs in this data field. Mt. Wilson luminosity classes are given as lower case letters in bytes 128-129. The "W" in Wolf-Rayet types is in byte 129 with the C or N in the following byte (130). In general, the temperature class (O, B, A, ..., S, C) occurs in byte 130 and the temperature subclass in byte 131 (intermediate sub-classes extend to 132-133 and other characters can be in bytes 131, ...). Characters normally appearing as lower case in standard notation, e.g. p, e, Si, Mn, Hg, Iab, are coded in lower case. A greek delta appearing for HD 189337 is coded as "@d". Note on n_RVel: the peculiarities are: V, V? - variable or suspected variable velocity; SB, SB1, SB2 - spectroscopic binaries, single or double lined spectra; O - orbital data available. One star (HD 2268) has a velocity with one decimal (0.5) stored there. Note on Dmag: magnitude difference between two components of a double, or between the two brightest components of a multiple system. Note on u_Dmag: this code takes the values V indicates variable magnitude difference, : uncertainty indicator (:); no occurrences at present. Note on n_Sep: "a" occurs if the separation refers to the semimajor axis . The colon (:) indicates, as usual, a large uncertainty. Note on PAcomp: this field may contain "ORB" to indicate an available orbit; hence, no PA. "SP" to indicate south preceding, "SF" to indicate south following, and "S" to indicate south. Note on Comp: Identification of components represented in bytes 185-188 and 191-195. The character "O" indicates an occultation binary.
