\IBVSabs{For 75 GCVS stars in Telescopium, we present revised information}
\IBVSabs{to be incorporated in the GCVS on-line version.}
\IBVSabs{This information is based on our analysis of the ASAS observations.}


\begintext

In the course of our work on revision of positional information
for all stars of the GCVS (Samus et al., 2002, 2003), we finished
identifications with positional catalogs for variables in the
constellation Telescopium. With accurate coordinates for these
stars, we were able to retrieve their observations from the
ASAS-3 data base (Pojmanski, 2002), often the only source of data
making it possible to study sufficiently bright southern
variables. These observations were analyzed using the
period-search software developed by Dr.~V.P.~Goranskij for
Windows environment. As a result, we obtained information
significantly appending or improving that in the GCVS for 75
stars (of 350 GCVS variables, including those from the
Name-Lists, in this constellation). In 57 cases, even the
variability types were modified or completely changed. The
relevant data are presented in Table~1. For short-period stars,
the light elements in the Table are heliocentric. The epochs are
minima for eclipsing and RV~Tauri stars and maxima for other
variables. Figures~1 and~2 contain sample light curves, plotted
using ASAS-3 $V$-band observations, for some of the variables.
Probably the most interesting of them are the two new RV~Tauri
stars, HI and NW~Tel, earlier classified respectively as E: and
I:,  and a very-short-period CWB (or a very-long-period RR)
variable PP~Tel ($P=1\fday1$).

The information presented in this paper, along with accurate
coordinates for all other GCVS stars in Telescopium, will be
incorporated in the GCVS on-line version in May, 2004.

\bigskip

We wish to express our sincere thanks to Dr.~V.P.~Goranskij for
providing us with his excellent period-search software. Thanks
are due to Dr.~M.L.~Hazen for sending us many unpublished finding
charts for Harvard variables. The work of the GCVS team is
supported, in part, by grants from the Russian Foundation for
Basic Research (grant 02-02-16069), The Federal Scientific and
Technological Program ``Astronomy'', the program ``Non-Stationary
Processes in Astronomy'' of the Presidium of Russian Academy of
Sciences, and the program of support for leading scientific
schools of Russia (grant NSh-389-2003-2).
