--------------------------------------------------------------------------------
Note (1): see file "refs", Table 3. This designation includes the
components of double or multiple stars (A, B, AB etc) in bytes 13-14
Note (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 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 1987A&AS...71..413M
'L' - if V is taken from other UBV sources.
Note (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 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'.
Note (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.

Historical Notes:
* 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
