Note on GalNo: Code identifying the galaxy.
This numbering system begins with 089, the first 88 codes being
reserved for constellations (cf. catalog ).
Note that NGC 1466 is a globular cluster (not a galaxy) between the
LMC and the SMC; we presented it separately, because it is not clear
to which galaxy to attribute its variable stars.
Note on VarNo: variable star No within the galaxy.
Number of the variable star in the galaxy. If in the literature for
the considered galaxy there exist several different variable star
numbering systems, we have introduced new numbers in the order of
increasing right ascension for the equinox 1950.0. But if the variable
star numbering system for the galaxy is practically of general use, we
have retained it - if necessary, with additional numbers ordered by
increasing right ascension.
Note on Name: Variable star Designation.
The name of the variable in the adopted system of variable star
designations: name of the galaxy + "V" + variable star No. within the
galaxy (see column VarNo)
Note on RAh, DEd:
If the star's coordinates are only roughly known, they are
nevertheless formally presented to one second of time in right
ascension (with the decimal point following) and to one arcsecond in
declination (with the decimal point following). See column u_DEs
which indicates the real accuracy.
Note on u_DEs:
the real coordinates accuracy uses the symbols:
(") means right ascensions accurate to one second of time and
declinations accurate to one arcsecond;
(:) means declinations accurate to one tenth of an arcminute;
(*) means declinations accurate to one arcminute.
(!) for V0474 in the Sculptor system, the listed coordinates
refer to the galaxy's center since the coordinates of the
star itself are unknown.
Note on VarType: type of variability.
The classification systems corresponds to the GCVS vols. I-III
(catalog ), with the addition of the new "BLBOO" type, called
after the prototype star BL Boo = NGC 5466 V19 referring to the
so-called "anomalous Cepheids", i.e. stars with periods characteristic
of comparatively long-period RRAB variables, but considerably brighter
by luminosity. There are also suspected variables designated by the
symbol "var:".
Note on l_magMin, magMin, n_magMin:
minMag contains the minimum brightness, or the variability amplitude
instead (in brackets, i.e. l_magMin='(' and n_magMin=')').
(<) means that minMag is an upper limit (light)
Note on magCode: designation of the photometric band.
P means photographic magnitudes,
V means visual or photovisual magnitudes as well as V system magnitudes.
In the latter case, they are usually distinguishable from visual
magnitudes by the number of digits after the decimal point (as a rule,
V system magnitudes are based upon photoelectric or CCD photometry).
Letters U, B, R, I, J, H, K, L, M, N, O, Q mean, as a rule, magnitudes
expressed in corresponding systems of broad-band photometry.
Note on Epoch:
The epoch expressed as a date of the Julian period (JD-2400000). For
eclipsing and ellipsoidal variables, RV Tau and RS CVn stars, the
catalogue gives epochs of minimum light, and for the rest of
variables, epoch of maximum light. If this rule is not fulfilled,
necessary explanations appear in Remarks. For novae and supernovae,
epochs of maximal brightness in Julian days are presented, followed by
years of outbursts (in brackets).
Note on l_P, P, l_P, n_P:
For U Gem stars and recurrent novae, the P column gives (in brackets)
the mean cycle value, if known.
Note on M-m/D, n_M-m/D:
Duration of light increase from minimum to maximum (M-m) for intrinsic
variable stars or the eclipse duration (D) for Algol type variables
are expressed in hundredths of the photometric period for the star in
question. An asterisk (*) in n_M-m/D means, for an eclipsing variable,
that the duration of the constant brightness phase in minimum (d) for
this star is equal to zero.
Note on SpType:
If there exist several spectral type determinations for a star, we
preferred more recent ones, taking into account reliability of each
determination. We converted symbols "d"
(dwarfs) and "g" (giants) into luminosity classes V and III. If a nova
showed spectral features typical of novae during or after the
outburst, a symbol (NOVA) is given in this column. If the spectrum
shows features characteristic of U Gem variables, this column contains
the symbol (UG). Continuous spectrum is designated "cont", the symbol
"e" means emission spectrum, lower case letters "ea", "eb" in this
column stand for "e alpha", "e beta". For RR Lyrae stars, spectral
types from hydrogen lines are given. A plus sign (+) between two
spectral type values means that spectra of two components of a
spectroscopic binary are observed. Two spectral type values separated
with a minus sign (-) mean the range of spectral type variations in
the process of brightness changes.
Note on nonMem:
Symbols "n" or "n:" for nonmembers (possible nonmembers) of the galaxy
in question. For the stars that enter the GCVS vols. I-III (catalogue
) or the NSV catalogue (catalog ) and are not members
of the corresponding galaxy, the present volume gives only the running
number, coordinates, the symbol "n", and the GCVS or NSV name.

Note on Gal:
"N" means NGC catalogue numbers,
"I" refers to the IC catalogue,
"U" to the UGC catalogue,
"M" to the MCG catalogue,
"E" to ESO survey lists.
"An" means an anonymous galaxy
"Intergal" is for cases when the supernova cannot be reliably
attributed to a particular galaxy and is considered intergalactic.
Note on u_DEs, u_DEsSN: the real coordinates accuracy is denoted by
(") means right ascensions accurate to one second of time and
declinations accurate to one arcsecond;
(:) means declinations accurate to one tenth of an arcminute;
(') means declinations accurate to one arcminute.
Note on maxDate, f_magMax:
The date of the SN's maximum or of discovery, or of an isolated
observation at high brightness.
If maxDate or f_magMax contains an asterisk (*), it means that the
date and/or the magnitude refer not to the maximum (not covered with
observations), but to the EPOCH OF DISCOVERY or to an isolated
observation at high brightness. As a rule, we did not include
information about maxima if it was based on considerable
extrapolation.

limited to types I (I-A, I-B) and II (II-l, II-pl), with possible
indications of peculiarities (pec).
Note on Discov:
In case of several discoverers, we give the name of the first author
of the discovery followed by "+" symbol. As a rule, we did not present
information on independent rediscoveries in the remarks, for the sake
of brevity. The abbreviation "BASST" in this column means that the
supernova was discovered by the Berkeley Automated Supernova Search
Team.
