grV light curve for 30 RR-Lyrae in the Kepler field
Listed in IVOA Registry (Virtual Observatory)
The aim of this work is to evaluate the performance of photometric metallicity [Fe/H], determined based on V-band light curves photometrically transformed from the gr-band light curves.
Description
We tested this by using a set of homogeneous samples of fundamental mode RR-Lyrae located in the Kepler field. It was found that the color term is necessary in such photometric transformation.
We demonstrated that when including the color term the determined photometric [Fe/H] are in good agreement with the spectroscopic [Fe/H], either based on the calibrated or the transformed V-band light curves. We also tested the impact of Blazhko RR-Lyrae in determining the photometric [Fe/H], and found that Blazhko RR-Lyrae can give consistent photometric [Fe/H]. Finally, we derived independent gVr-band [Fe/H]-ph31-P relations (where ph31 and P are the Fourier parameter and pulsation period, respectively) using our light curves.

The V-band relation is in good agreement with the most recent determination given in the literature.
