Description:
This Catalogue is an update to Helen Sawyer Hogg's Third Catalogue on
Variable Stars in Globular Clusters (1973, David Dunlap Observatory
Publications, Volume 3, Number 6: 1973PDDO....3....6S 1973PDDO....3....6S; see Cat V/97;
see also Clement+, 2001AJ....122.2587C 2001AJ....122.2587C).
This catalogue is based on the individual cluster files downloaded on
http://www.astro.utoronto.ca/~cclement/cat/listngc.html on the
01-Feb-2017. Later updates are indicated in clusters.dat; column "Update".
Acknowledgements:
When using this catalog, please cite Clement et al. 2001AJ....122.2587C 2001AJ....122.2587C
and the date of the update for a particular cluster.

Note on variabls.dat: The data for the stars are based mainly on the references
listed in refs.dat for each cluster. Exceptions are indicated in the Notes on
clusters.
Note on notedisc.dat: This table corresponds to the section
"Discovery of the Variable Stars" where I cite the discovery paper for each
variable and indicate how the author identified the variable in his or her
"discovery paper". If there is confusion about the identification of a
particular variable, the original papers should be considered the primary
source for acquiring information.

Note (1): The name of the file (on http://www.astro.utoronto.ca/~cclement/cat/)
indicates the IAU cluster name, in the format CHHMMpDDd or CHHMMmDDd,
where the "p" and "m" indicate plus or minus, as there may be
difficulty in naming files with "-" or "+" on host systems.
Note (2): Many of the positions are from a "catalogue of equatorial coordinates
for variable stars in globular clusters" published by Samus and his
collaborators (2009, J/PASP/121/1378). Their catalogue also includes
cross-identifications for globular cluster variables listed in the
GCVS (see Samus+, 2007-2013, B/gcvs).
Note (3):
a = This object is no longer classified as a Milky Way globular cluster.
It is not included in the 2011 update to the variable star catalogue.

Note (1): For C1714m237, the position of #2 is 17 17 57.8 -23 4t 36 has been
corrected for 17 17 57.8 -23 46 36 and for C0512m400, the position
of #54 is 05 14 09.11 -40 02 54.d has been corrected for
05 14 09.11 -40 02 54.6.
Note (2): Epoch for position as follows:
R0 = RA, DEC in the J2000 coordinates (5521 instances)
R5 = RA, DEC in the 1950 coordinates (0 instance)
= Blank means no position (62 stars) or positions X, Y in arcsec (21 stars)
Note (3): "CST" denotes non variable stars previously designated as variables.
For the classification of the variable type, I have used (in most cases) the
scheme proposed by N. N. Samus at the IAU XXVIth General Assembly, Prague
2006: The draft classification (version August 9, 2006) for the new GCVS
versions (http://www.sai.msu.su/gcvs/future/classif.htm).
Throughout the last few decades, a number of pulsars (PSR) have been
discovered in Galactic globular clusters. Paulo Freire maintains an
up-to-date list of pulsars in globular clusters on his website
(http://www.naic.edu/~pfreire/GCpsr.html).
