Abstract:
The nearly continuous light curves with micromagnitude precision
provided by the space mission Kepler are revolutionizing our view of
pulsating stars. They have revealed a vast sea of low-amplitude
pulsation modes that were undetectable from Earth. The long time base
of Kepler light curves allows for the accurate determination of the
frequencies and amplitudes of pulsation modes needed for in-depth
asteroseismic modeling. However, for an asteroseismic study to be
successful, the first estimates of stellar parameters need to be known
and they cannot be derived from the Kepler photometry itself. The
Kepler Input Catalog provides values for the effective temperature,
surface gravity, and metallicity, but not always with sufficient
accuracy. Moreover, information on the chemical composition and
rotation rate is lacking. We are collecting low-resolution spectra for
objects in the Kepler field of view with the Large Sky Area
Multi-Object Fiber Spectroscopic Telescope (LAMOST, Xinglong
observatory, China). All of the requested fields have now been
observed at least once. In this paper, we describe those observations
and provide a useful database for the whole astronomical community.
Description:
Four observation seasons of the Kepler FOV were needed - from 2011 to
2014 - to finish the first round of observations for the
"LAMOST-Kepler project" (LK-project). A total of 38 plates were
observed on 27 different observation nights.

Note (1): Target type as follows:
E = Extra target;
P = planet target;
K = KASC target (targets in the Kepler FOV selected by the
Kepler Asteroseismic Science Consortium (KASC));
S = standard target;
F = Field target.
Note (2): Slit position as follows:
x1 = fiber slit uses the full slit width (R=1000);
x2/3 = fiber slit is limited to 2/3 (R∼1800) of slit width;
x1/2 = fiber slit is limited to half (R=2000) of the slit width.
Note (3): The first two numbers refer to the reduction pipeline and the last
number to the analysis pipeline.
Note (4): In general, it corresponds to the right ascension of the object as
given in the target list (epoch 2000.0) except for a fraction of the
targets brighter than magnitude 11, for which an offset is added
to the pointings of the fibers to avoid saturation.
Note (5): The entry "+99.99" means that SNR>100 but that the exact value
is not given.
