Abstract:
The first supplement (MDSPS1) to the Catalog of Metal-Deficient F-M Stars
Classified Spectroscopically (MDSP) includes 289 stars selected from the
literature sources published in 1997-1982.
Introduction:
Recorded information includes MDSPS1 number, star numbers in 2 catalogs
with notes on duplicity, V magnitude, (B-V)0 color, Mv, B-V color excess
and [Fe/H], notes on colors and metallicity, stellar group, spectral type
with reference, coded catalog number, original equinox and format codes
for the equatorial coordinates, RA and Dec (1950.0) in radians, RA and Dec
(1900.0, 1875.0, 1855.0), HD, BD/CD, G, LTT, and up to 13 other catalog
designations in a numeric code.

Note (1): values are:
1 = Photovisual magnitude
2 = Photographic magnitude
3 = Red magnitude
4 = noticeable uncertainty (marked by a colon : in the printed catalogue)
Note (2): values are:
1 = value transformed from photometry in Vilnius, Geneva, uvby
and DDO systems
2 = noticeable uncertainty
Note (3):
1 = noticeable uncertainty (marked by a colon : in the printed catalogue)
2 = large uncertainty (marked by two colons :: in the printed catalogue)
Note (4): the group dependence was defined on the basis of all
available information concerning the star: photometric and
spectroscopic classification, kinematic properties, etc, see
description in Bartkevicius, Vilnius Obs. 1983VilOB..64...24B 1983VilOB..64...24B and
1984VilOB..66....3B 1984VilOB..66....3B; some new abbreviations have been applied:
"MD-I" denote metal-deficient supergiants, and "MDD" denote
dwarfs with moderate metal deficiency ([Fe/H]>-0.6).
Note (5):
The photometric spectral type is marked by a symbol "PH" (an asterisk
refers to a type determined in this paper). It the spectral type is
obtained from both spectroscopic and photometric classifications, the
symbol "SP,PH" is used. For stars with [Fe/H] values obtained from
high-dispersion spectra, the symbol "MD" is used and the [Fe/H] value
is given in parentheses behind. For some stars the spectral type from
HD, SAO, AGK2, BS, and other catalogues are presented without any
references.
Note (6): the Original Equinox is coded as:
0 = 1950.0; 1 = 1855.0; 2 = 1875.0; 3 = 1900.0
4 = 1925.0; 5 = 1975.0; 6 = 2000.0
Note (7): positions marked with "1" are listed to 0.1min in RA
and 1arcmin in Dec accuracy.
Note (8):
See the file "numsys.txt" for keys to the coded identifications,
and file "srccats.txt" for the acronyms used for catalogues.

History:
* 11-Dec-2000: Only one equatorial position (for Equinox B1950.0) was
kept in file data.dat -- the original file contained in addition the
equatorial positions for equinoxes 1900, 1875 and 1875, plus the 1950
RA and Dec in radians.
