Abstract:
In this paper, we report on observations of the CoRoT LRa1 field with
the Berlin Exoplanet Search Telescope (BEST). The current paper is
part of a series of papers describing the results of our stellar
variability survey. The BEST is a small aperture telescope with a wide
field of view (FOV). It is dedicated to searching for stellar
variability within the target fields of the CoRoT space mission to aid
in minimizing false-alarm rates and identify potential targets for
additional science. The LRa1 field is CoRoT's second long run field
located in the galactic anticenter direction. We observed the LRa1
stellar field on 23 nights between November and March 2005/2006. From
6099 stars marked as variable, 39 were classified as periodic variable
stars and 27 of them are within the CoRoT FOV. We also confirmed the
variability for four stars listed in the General Catalogue of Variable
Stars (GCVS).
Description:
The LRa1 was observed between 2005 November 21 and 2006 March 6. The
total time baseline of our observations spreads over 104.937days.

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
