Abstract:
We report on observations of the COROT IR01 field with the Berlin
Exoplanet Search Telescope (BEST). BEST is a small-aperture telescope
with a wide field of view (FOV). It is dedicated to searching for
variable stars within the target fields of the COROT space mission to
aid in minimizing false-alarm rates, and identifying potential targets
for additional science. COROT's observational program started in 2007
February, with the "initial run" field (IR01) observed for about 2
months. BEST observed this field for 12 nights spread over 3 months in
winter 2006. From the total of 30,426 stars observed in the IR01
field, 3769 were marked as suspected variable stars, and 54 of these
showed clear periodicity. From these, 19 periodic stars are within the
part of the COROT FOV covered in our data set.
Description:
BEST is operated by the Institute fuer Planetenforschung of the
Deutsches Zentrum fuer Luft- und Raumfahrt (DLR) and was located in
Tautenburg, Germany, from 2001 until 2004. It was then relocated to
the Observatoire de Haute-Provence (OHP), France. BEST started to
regularly observe from OHP in early 2004, with a maintenance period of
3 months in summer 2006 which was without observations. Since autumn
2006 the telescope has been operated in remote control mode by an
observer from Berlin. The primary goal of the observations is to
identify new variable stars in the target field of the COROT mission.
We observed the IR01 field from the beginning of November, when it
began to be above the horizon for more than 3hr. The observing
campaign finished in mid-December.

Note (2): Magnitudes correspond to a wide R filter (650-800nm),
calibrated against the USNO-A2 catalog (I/252) only.
Note (3): Variability class as follows:
CEP = Cepheid
DSCT = Variable of the Delta Scuti type
EA = Algol (Beta Persei)-type eclipsing system
EB = Beta Lyrae-type eclipsing system
ELL = Rotating ellipsoidal variable
EW = W Ursae Majoris-type eclipsing variable
