Abstract:
We present the largest Cepheid sample in M31 based on the complete
Pan-STARRS1 survey of Andromeda (PAndromeda) in the rP1, iP1, and
gP1 bands. We find 2686 Cepheids with 1662 fundamental-mode
Cepheids, 307 first-overtone Cepheids, 278 type II Cepheids, and 439
Cepheids with undetermined Cepheid type. Using the method developed by
Kodric et al. (2013, , Cat. J/AJ/145/106), we identify Cepheids by
using a three-dimensional parameter space of Fourier parameters of the
Cepheid light curves combined with a color cut and other selection
criteria. This is an unbiased approach to identify Cepheids and
results in a homogeneous Cepheid sample. The period-luminosity
relations obtained for our sample have smaller dispersions than in our
previous work. We find a broken slope that we previously observed with
HST data in Kodric et al. (2013, , Cat. J/AJ/145/106), albeit with a
lower significance.
Description:
Light curves, fit parameters and cross matching tables of the
PAndromeda Cepheid survey in M31 in the r_P1, i_P1 and g_P1 bands.

Note (1): See section 3 in Kodric et al. (2013AJ....145..106K 2013AJ....145..106K).
Note (2): All epochs are required to have a signal to noise ratio of larger
than two and the corresponding visit stack has to have more
than 2 frames.
Note (3): Of the Fourier fit to the light curve.
Note (4): i.e. not extinction corrected as the rP1,0 magnitude but also
determined with with the mean flux of the light curve converted
to magnitude.
Note (5): Obtained from the error of the Fourier decomposition.
Note (6): Of the first two Fourier coefficients (see Kodric et al.,
2013AJ....145..106K 2013AJ....145..106K) equation 6).
Note (7): Fourier coefficients in the rP1 and iP1 bands as defined in
equation 3 in Kodric et al. (2013AJ....145..106K 2013AJ....145..106K). The order of the
fits is N=5 so there are 11 Fourier parameters. The order of the fits
for the gP1 band is N=3 but there are still 11 columns where the
columns for the higher orders are set to a default value of -1.
Note (8): Flag as follows:
C = Catalog member
R = Rejected member
