Abstract:
The Kepler Mission (launched in 2009 March) provides nearly continuous
monitoring of ∼156000 objects with unprecedented photometric
precision. Coincident with the first data release, we presented a
catalog of 1879 eclipsing binary systems identified within the
115deg2 Kepler field of view (FOV). Here, we provide an updated
catalog from paper I (Prsa et al. 2011, Cat. J/AJ/141/83) augmented
with the second Kepler data release which increases the baseline
nearly fourfold to 125 days. Three hundred and eighty-six new systems
have been added, ephemerides and principal parameters have been
recomputed. We have removed 42 previously cataloged systems that are
now clearly recognized as short-period pulsating variables and another
58 blended systems where we have determined that the Kepler target
object is not itself the eclipsing binary. A number of interesting
objects are identified. We present several exemplary cases: four
eclipsing binaries that exhibit extra (tertiary) eclipse events; and
eight systems that show clear eclipse timing variations indicative of
the presence of additional bodies bound in the system. We have updated
the period and galactic latitude distribution diagrams. With these
changes, the total number of identified eclipsing binary systems in
the Kepler FOV has increased to 2165, 1.4% of the Kepler target stars.

Note (1): A cross-check against the short-period pulsators presented in
Debosscher et al. (2011, Cat. J/A+A/529/A89) yielded 42 objects which
were removed from the EB catalog (see Section 2.2).

Note (1): 58 of the objects included in the first catalog
(Paper I, Cat. J/AJ/141/83) were found to be blended systems where the
target star is not itself an eclipsing binary.
