The filters of the Vilnius system are: ------------------- Filter Lambda Width (A) (A) ------------------- U 3450 400 P 3740 260 X 4050 220 Y 4660 260 Z 5160 210 V 5440 260 S 6550 200 -------------------

LID Code-number in the Lausanne/Geneva system number=1 see file "refs", Table 3. This designation includes the components of double or multiple stars (A, B, AB etc) in bytes 13-14 --- DM Durchmusterung (BD/CD/CPD) numbers. --- Name Bayer or GCVS (variable) name of star. --- VarFlag 'VAR' - for variable star included in GCVS, 'VAR?' for stars suspected of variability. --- VarType Type of Variability taken from GCVS. --- RAh Right Ascension 1950 (hours) h RAm Right Ascension 1950 (minutes) min RAs Right Ascension 1950 (seconds) s u_RAs ':' if precision of equatorial coordinates is less than 1s. --- DE- Declination 1950 (sign) --- DEd Declination 1950 (degrees) deg DEm Declination 1950 (minutes) arcmin Vmag The magnitude V. mag u_Vmag ':' if precision of Vmag less than 0.03 mag., 'V' for variable --- r_Vmag Source of V magnitude number=2 Source of Vmag is coded as follows: blank - if V is measured in the Vilnius-system, 'N' - if V is taken from the catalogue of B. Nicolet (1978) =1978A&AS...34....1N 'M' - if V is taken from the UBV Photoelectric Photometry Catalogue of J.C. Mermilliod (1986) (CDS Catalogue: II/122B) =1987A&AS...71..413M 'L' - if V is taken from other UBV sources. --- U-P U-P photometric index mag u_U-P Uncertainty flag (:) on U-P --- P-X P-X photometric index mag u_P-X Uncertainty flag (:) on P-X --- X-Y X-Y photometric index mag u_X-Y Uncertainty flag (:) on X-Y --- Y-Z Y-Z photometric index mag u_Y-Z Uncertainty flag (:) on Y-Z --- Z-V Z-V photometric index mag u_Z-V Uncertainty flag (:) on Z-V --- V-S V-S photometric index mag u_V-S Uncertainty flag (:) on V-S --- Nobs Number of measurements. --- STD 'S' for Standard star --- r_SpType Source of spectral classification number=3 Source of the spectral classification is as follows: blank - from the Vilnius photometric system, 'J' - from M.Jaschek Catalogue of Selected Spectral Types in the MK system (CDS Catalogue: III/42) =1978BICDS..15..121J 'K' - from P.M.Kennedy MK Classification Extension Catalogue (Mount Stromlo, Australia, ed. 1978) 'L' - from other sources. The preference is given to M.Jaschek catalogue if the same star has different spectral classifications in references. Exception is made for the Bright Star Catalogue, GCVS and General Catalogue of Cool Carbon Stars of C.B. Stephenson (Publ. Warner and Swasey Obs., Vol. 1, No. 4, 1973). In such cases the spectral classification is taken from these catalogues and are marked 'L'. --- SpType Spectral classification number=4 in addition to normal spectral classes O, B, A, F, G, K, M and luminosity classes Ia, Ib, Iab, II, III, IV, V, the following designations are used: R,N,C - Carbon stars, S - Zirconium stars, CN - Cyanogen stars, WR, WC, WN - Wolf-Rayet stars, DO, DB, DA, DZ, DQ - White dwarfs of different types. The next designations are added to main spectral classification to mark some peculiarities in spectrum: P - peculiarity in spectrum, E - emission in spectrum, M - metallic-line star, N - spectral lines widened by axial rotation, S - narrow spectral lines, BA - Barium stars, CH - stars with strong G-band, MD - metal-deficient star, NN - very wide spectral lines, OF - emission-line O-type star, SB - spectroscopic binary star, SD - subdwarf (dwarf with large metal-deficiency) WG - stars with weak G-band, BHB - blue horizontal branch star, RHB - red horizontal branch star, MDE - extreme metal-deficient star, MDG - metal-deficient giant, MDGE - extreme metal-deficient giant, MDSG - metal-deficient subgiant, MDSGE - extreme metal-deficient subgiant, SHELL,SH - shell-star. The absence of spectral classification means that either no spectral classification is known for given star, or the star is impossible to classify photometrically. --- Ref Reference for measurement in the Vilnius photometric system (see file "refs", Table 2) --- Francois Ochsenbein CDS 1995Oct02 UNKNOWN UNKNOWN * December 1989: tape received at CDS from Moscow Astronomical Data Centre * 02-Oct-1995: description standardized at CDS; a few errors have been detected and corrected: - 'null' characters converted to blanks - the "ST" (standard stars) initially in bytes 111-112 moved to byte 113 - the missing decimal points in DEm column have been added - a "/" character appearing in byte 71 of record #1629 (1.00090068) changed to a blank - a ":" character appearing in byte 80 of record #4593 (6.20205021) changed to a blank II_157A.xml
