================================================================================
ADC_Keywords: Stars, variable;
Description:
This catalog is a compilation of 11206 stars suspected of variability
and not finally designated as variables prior to 1997. It is the
supplementary part to the "New Catalogue of Suspected Variable Stars"
published in 1982 (Kukarkin et al., file "nsv.dat" included here).
Data contained in the present catalog include positions, magnitudes,
variability types, references to the literature, spectra and
cross-identifications. The computer version of the NSV Supplement
contains principally the same data as the printed catalog, the data
tables with the textual material (bibliography, remarks) are included.

Note on RemFlag: There are several data fields that can contain
asterisks. These signify that more complete information will be found
in the remarks to the published catalog. The remarks are machine
readable, they do contain much supplemental information. There, one
will find information covering situations like, e.g.:
1. The discoverer of the light variability is not the author of the
paper cited in the variability reference, or is one of several
authors of the paper cited. In these cases, discoverers' names are
given in original transcriptions of the remarks.
2. The most important additional information about a star, although
the NSV Supplement compilers did not intend to present complete
bibliographies for any catalogued stars.
3. Remarks for visual binaries giving visual magnitudes for the
individual components A and B, angular separations, and position
angles for faint components (or semimajor axis of a relative orbit
and period of orbital motion). Then, data for other components are
given where applicable. (Combined magnitudes are generally reported
in the machine-readable table.)
Note on u_DEs: The actual accuracy of coordinates is indicated with
the symbols: (:) means right ascensions accurate to one second of
time and declinations accurate to one tenth of an arcminute;
(*) means declinations accurate to one arcminute.
Note on magMax, magMin: The star's magnitude in minimum and maximum
brightness. Instead of the magnitude in minimum, the star's amplitude
of variation may be indicated (in brackets). Magnitudes are reported
to hundredths if the observations are photoelectric or CCD, to tenths
or whole magnitudes if they are not. If only an amplitude has been
measured photoelectrically, then the maximum magnitude is generally
given to tenths only and the minimum is reported to hundredths.
Note on n_magMin and magCode: The photometric system in which magMin
and magMax are reported. The main codes are V (visual, photovisual,
or Johnson's V), B (Johnson's B) and P (photographic magnitudes). The
designations u, v, b, y refer to the Stroemgren system. The symbols
Ic, Rc mean magnitudes in Cousins' I, R system; Hp, T - in Hipparcos
and Tycho mission systems; J, H, K, L, M - infrared magnitudes.
Note on VarType: Type of variability. The system of variable star
classification corresponds to the GCVS4, with six additions (ZZO, AM,
R, BE, LBV, BLBOO) introduced in the Name-Lists 67-72 and in the GCVS
vol.V. Brief descriptions only are given here:

Note on r_NSV: The four digits give the number in the list of references
contained in the catalog, which is generally the first publication
announcing the possible variability.
Note on Ref2: The coding for the numbers is similar to that used in
the variability references described above, except that there are also
letter codes. These are references to papers containing
identification chart or photograph of the field with the suspected
variable marked. If the cited paper does not contain a chart, but the
star is catalogued in one of the Durchmusterungen (BD,CD,CPD) or in the
Hubble Space Telescop Guide Star Catalog (GSC), then corresponding
letter codes DM or GSC are given.
Note on SpType1: Spectral types, subtypes and luminosity
classes are given. More detailed classification information is given
in the remarks to the catalog. Also the following symbols are used:
AF A-F
cont continuum
e emission spectrum
ea e sub alpha
FG F-G
KM K-M
* see Sp type in remarks
Note on VarName:
The alternative name of the variable. All necessary information on
the star is to be found under that alternative name in Cat. <II/214>

Note on ID: all identifications needed to find the star in the papers
with the first (or independent) announcement of the discovery of its
variability. References to these papers (see file refs.dat) are given
in square brackets after the corresponding identification. The name
of the discoverer accompanies the reference only in the case of its
being different from the name of the author(s) of the paper referred
to. Designations of components of double or multiple system: A, B,
C, ..., A1, A2, ..., p - preceding, f - following, s - southern, n -
northern. The transliterations of greek letters are used: alpha,
beta, gamma,..., omega, etc., kappa 2, omicr 1. Different
identifications of the same star with catalogs and lists are separated
with equality sings (=). Symbol (?) marks the doubtful
identification. The following catalogs abbreviations are used (abbreviated

There are several data fields that can contain asterisks. These signify
that more complete information will be found in the remarks to the
published catalog. The remarks are, unfortunately, not machine
readable, but they do contain much supplemental information. There, one
will find information covering situations like, e.g.:

paper cited in the variability reference, or is one of several authors
of the paper cited. In these cases, discoverers' names are given

2. The most important additional information about a star, although the
NSV compilers did not intend to present complete bibliographies for any
catalogued stars.

star in the corresponding catalog) giving visual magnitudes for the
individual components A and B, angular separations, and position angles
for faint components (or semimajor axis of a relative orbit and period
of orbital motion). Data for other components are then given where
applicable. (Combined magnitudes are generally reported in the
machine-readable table.)
Note on RAh, RAm, RAs, DE-, DEd, DEm, DEs:
The position is also listed when the variable is equivalent to a GCVS
star (column VarName).
Note on u_DEs:
The actual accuracy of coordinates is indicated with the symbols:
(:) means right ascensions accurate to one second of time and
declinations accurate to one tenth of an arcminute;
(*) means declinations accurate to one arcminute.
Note on VarType: type of variability (see file ...\III\vartype.txt).
The system of variable star classification corresponds to the GCVS4,
with six additions (ZZO, AM, R, BE, LBV, BLBOO) introduced in the
Name-Lists 67- 72 and in the GCVS vol.V. (see "Note on VarType" section
above)
Note on magMax, magMin: Magnitudes are reported to hundredths if the
observations are photoelectric, to tenths or whole magnitudes if they
are not. If only an amplitude has been measured photoelectrically, then
the maximum magnitude is generally given to tenths only and the minimum
is reported to hundredths.
Note on magCode: the photometric system in which magMin and magMax are
reported (see also Note on n_magMax, n_magMin). The main codes are P
(photographic magnitudes) and V (visual, photovisual, or Johnson's V).
See also the documents by Kholopov et al. (1985-1988) or Warren (1988).
Note on Ref1: Usually a 6-digit number coding, as a rule, the reference to the
announcement of the discovery of variability. The first two digits give the
year (in the 20th century) when the announcement was published (blank
for the 19th century). The next four digits give the number in the list
of references contained in the published catalog, which is generally the
first publication announcing the possible variability. The numbers are
followed by a letter code in most cases (byte 75) with the following
meanings:
K: the cited paper contains a chart or photograph of
the field with the suspected variable marked.
D: the cited paper does not contain a chart, but the
star is catalogued in one of the Durchmusterungen
(DM) (BD,CD,CPD).
Note on Desig: The identification of the suspected variable in the
paper referenced above. DM numbers are given without a prefix, the
standard naming convention of "The Henry Draper Catalogue" being used
(BD for zones +89 to -22; CD for -23 to -51; CP for -52 to -89).
Some identifications are given by coordinate designations, a 6-digit
number consisting of hours, minutes, and seconds (or tenths of a minute)
of time and degrees of declination with sign included. An asterisk (*)
signifies that a designation is given in the remarks to the published
catalog.
Stars are sometimes designated with numbers from the catalogs of Zinner
(ZI, 1929) and Prager (PR, 1934, 1937) because the original discovery
publications were not available to the NSV compilers. The catalogs of
Zinner and Prager give detailed references to early observations of such
stars.
Note on SpType: Spectral types and subtypes only are given.
Most luminosity classes are III to V, but if a star is a supergiant,
more detailed classification information is given in the remarks to the
published catalog. The following symbols are used:
AF A-F
AM Am
AP Ap
BE Be
E emission spectrum
EA e sub alpha
EV variable emission in spectrum
FG F-G
KM K-M
OF Of
PD Pd
T characteristics of T Tauri stars
Note on Ref2: The coding for the numbers is similar to that used
in the variability references described above, except that there are no
letter codes. These are references to papers containing identification
charts if no charts are given in the papers cited for the variability
references.
Note on VarName, NoteFlag2:
1) The alternative name of the variable. All necessary information on
the star is to be found under that alternative name, in the iii.zip and
nl.zip files.
2) The star's name in the GCVS Vol. V (see the file v.zip, where the
explanation of the designations is also given). In this case, the
symbol "*" in column 89 means the presence of remarks in Vol. V.

History:
* 16-Jun-1999: in file nsv.dat, the star NSV 7334 = HV 10762 which was
erroneously cross-identified with QW Nor, was corrected at CDS (the
original data of the 1982 version of the NSV catalogue were inserted
for this star)
QW Nor is identical to NSV 7374.
