\begintext

The General Catalogue of Variable Stars (Kholopov et al.,
2004) still contains many variables for which the
elements are completely or partly unknown. In the New
Catalogue of Suspected Variable Stars (NSV) (Kukarkin,
Kholopov, 1982) and its supplement (Kazarovets, Samus,
Durlevich 1998) there are another 25000 variables -- approximately -- 
that need further investigation.
In this investigation, a group of variables was selected
from the GCVS and some from the NSV and supplement
catalogues to find the elements, or additional elements
for them.

Data from the ASAS-3 database (Pojmanski, 2002), as well
as from NSVS (Wozniak et al., 2004) and Hipparcos
(Perryman et al., 1997) were used. In 15 cases a
combination of data was used to make a better analysis
possible. Hipparcos magnitudes were transformed to the V
system (Otero, 2001).

NSVS magnitudes were shifted to match the maximum light
of the ASAS-3 data for these variables. For 2 cases the
ASAS and NSVS magnitudes were shifted to match the
maximum light of the Hipparcos observations.

In almost all cases ASAS-3 data were used from the
diaphragm appropriate for the magnitude of the variable.
Only in the case of  DV Cen a set of data from another
diaphragm was used to avoid contaminated data. In all
cases only data with ``A'' and ``B'' status in ASAS-3 were
used. Flagged NSVS and Hipparcos data were avoided as
well. Elements for the variables were found with AVE
(Barbera, 1999).

Data for the selected stars were taken from the online
version of the GCVS, to ensure most recent data on
positions of the variables.

Identification in ASAS-3 was done by limiting the search
radius in ASAS-3 query field to 5 arcseconds. In a few
cases the search radius needed to be expanded to 10 or 15
arcseconds, before a matching star in the ASAS-3 database
was found. These stars are labeled in Table 1 with 1 and
2 asterisks respectively following the name of the variable. A
search radius bigger then 15 seconds was considered an
identification issue, that would need resolving before
continuing the investigation. Only 12 variables needed a
15 arcseconds search radius.

Similarly, identifications in NSVS were done by using a
search radius of 6 arcseconds. No bigger search radius
was needed here.

All variables were identified in VizieR by their matching GSC numbers 
(see Table 2). In four cases, where there was no GSC identification, 
the UCAC2 catalogue in VizieR was used for identification.

As many of the variables as possible were identified by
their original identification chart as well, but this was
not possible for all. In total, of the 69 variables in
Table 1, the position of 40 of them could be checked by
using the original identification chart. In case the
identification created a problem some comments were added
in the Remarks section of this publication.

Data from ASAS-3, NSVS and Hipparcos were transferred to
Excel, and then into AVE for analysis. Many light curves
exhibit an unusual amount of noise and many secondary
minima are not well defined. General problems with the
ASAS-3 system, faintness or contamination by close
neighbouring stars are the main cause.

In many cases there are observed minima in the original
discovery publications, but it was not attempted to link
them to the present newly found elements. A period with 5
significant digits, cannot be used to connect with minima
observed in the 1930's or 40's.\\

Information about deviating duration of the secondary
minimum, and duration of total eclipse, is given in the
remarks section.

The epoch of minimum light was obtained by using the
bisected chords method on the folded light curve.
For every variable, there is a folded light curve, based
on the ASAS-3, NSVS or Hipparcos measurements.\\


{\bf Remarks}\\


\noindent V502 Ara: the position given in the original publication:
(1875) 17\hr 04\mm 16\sec, $-$54\deg 46\farcm1, is the position of the star
2UCAC08136035, but this is not the star on the
identification chart. That is 2UCAC08136018 at
17\hr 14\mm 28\fsec2, $-$54\deg 55\arcm 29\farcs2. 
This is close to the position
given by the GCVS and by ASAS and this was adopted for
this investigation.\\
V534 Aur: previously derived period 1.4280d based on part
of the light curve in Han (2000). The two minima in this
publication seem to confirm these elements. The period
could be twice the value given in the table.\\
V518 Cas: DII=2.7 \%. Very steep ascending and descending
branches. There could be a short period of totality, but
this part of the light curve is not in the data.\\
DV Cen: Because data from a different diaphragm were
used, the magnitudes given could be slightly different
from V.\\
V413 Cen: The period could be twice the value given in
the table.\\
RR Cir: wrongly identified as GSC 09016-01864 in Simbad.
That star is also slightly variable according to the ASAS-3 data.\\
RR Col: DII=2.8 \%. Reported as `missing' by Dvorak
(2004). Primary and secondary minima are almost
equally deep, so the primary minimum could be the
secondary.\\
DF Dra: Very distorted light curve.\\
TU Lup: Very steep ascending and descending branches.
There could be a period of totality, but this part of the
light curve is not in the data.\\
CY Oph: Reported as `missing' by Dvorak (Dvorak, 2004).
Duration of secondary minimum is very short, it needs to
be observed properly.\\
FG Oph: The period could be twice the value given in the
table.\\
V983 Oph: Primary and secondary minima are almost equally
deep, so the primary minimum could be the secondary.
Only five measurements during minima.\\
V1027 Ori: DII=4.8\%. Identification chart in Olijnik
(1963) has wrong scale written in chart. Primary and
secondary minima are almost equally deep, so the primary
minimum could be the secondary.\\
KK Pup: The period could be twice the value given in the
table.\\
DM Sgr: =V1162 Sgr. Reported as identical in GCVS, but
still have separate positions in Simbad.\\
V4727 Sgr: Very steep ascending and descending branches.
There could be a period of totality, but this part of the
light curve is not in the data.\\
V761 Sco: Finder chart in Astronomische Nachrichten is
not accurate enough to distinguish between several
neighbouring stars. Identification was based on
coordinates from GCVS.\\
CK Vel: Reported as `missing' by Dvorak (2004).
The period could be twice the value given in the table.\\
GT Vel: DII=3.2\%\\
NSV 5499: Possibly same object as X-ray source RX
J1212.2+6853\\
NSV 25346: The period could be twice the value given in
the table.\\

The eccentricity (Min II phase) given for V983 Oph in Table 1 in IBVS 5652 
should read 0.269 instead of 0.731.
