Abstract:
The Berlin Exoplanet Search Telescope is a small-aperture, wide-field
telescope dedicated to time-series photometric observations. During an
initial commissioning phase at the Thueringer Landessternwarte
Tautenburg, Germany, and subsequent operations at the Observatoire de
Haute-Provence, France, a 10°2 circumpolar field close to the
galactic plane centered at (RA, DE) = (02:39:23, +52:01:46) (J2000.0)
was observed between 2001 August and 2006 December during 52 nights.
From the 32129 stars observed, a subsample of 145 stars with clear
stellar variability was detected out of which 125 are newly identified
variable objects. For five bright objects, the system parameters were
derived by modeling the light curve.
Description:
The target field was observed with BEST from the Thueringer
Landessternwarte (TLS) site between 2001 August 15 and 2003 March 13
during 25 nights for a total of 70hr. After the relocation of BEST to
OHP in 2004 the same field was observed between 2005 November 7 and
2006 December 20 during 27 nights for a total of 87hr.

Note (1): Source flag as follows:
c = Star affected by crowding;
k = Previously known object. Identification from VSX or GCVS can be
found in the last column, OName.
Note (2): The epoch T0 is given in reduced Julian date with respect to
T=2450000.0. It denotes the first minimum in the light curve.
