Abstract:
The catalog is a result of the analysis of VI photometry obtained
during the first 17-month observations in the ASAS3-North station. The
variable stars we present are divided into eleven groups according to
the presented variability; the groups are briefly discussed. The
catalog is intended to be a source of information for target selection
process and follow-up programs.
Description:
The data analyzed in this paper were obtained in the ASAS3-North
station located at Haleakala (Maui, Hawaii Islands USA) using two
wide-field instruments, equipped with Nikkor 200-mm f/2.0 lenses and
Apogee AP-10, 2048x2048 CCD cameras, collecting data in two filters,
V and I. The data cover roughly 500 days between July 2006 and
December 2007.

Note (1): Master ASAS identification coming from the equatorial coordinates
of the object (epoch 2000.0) in the abbreviated form.
Note (2): Right ascension and declination are given with the accuracy of
0.00001° for objects identified with 2MASS sources and with the
accuracy of 0.0001° for the remaining stars. The latter means that
a star is a blend and we are not sure which star of two (or more)
objects is variable.
Note (3): Entries are given only if a star was identified with a 2MASS
source and the photometric quality flag was equal to A, B, C or D.
Note (4): Note, please, that the range of variability for periodic stars
was derived from phase diagrams in which the shape of the light curve
was approximated by a truncated Fourier series and the outliers from
such a fit were rejected. Unfortunately, this procedure usually
removed points in the very deep and narrow minima of eclipsing
binaries (mainly of EA type) thus leading to underestimation of
derived range. On the other hand, the ranges of variability for stars
identified as APER, QPER and MIRA were derived from the original light
curves. In this case, the presence of outliers might lead to
overestimation of the range of variability.
Note (5): The stars were cross-identified with the following sources of
variability in this area of the sky:
(1) : General Catalogue of Variable Stars (GCVS, Cat. B/gcvs), e.g. HO Lyr.
(2) : New Catalogue of Suspected Variable Stars, including the
Supplement (Kazarovets et al., 1998, IBVS 4655), Cat. II/219.
