Parameter catalogs of "Photometric Metallicity and Distance Estimates for ∼70,000 RR Lyrae Stars from Zwicky Transient Facility"

Data Abstract Here are the parameter catalogs of RR Lyrae stars from the paper "Photometric Metallicity and Distance Estimates for ∼70,000 RR Lyrae Stars from Zwicky Transient Facility". The paper contains two main catalogs. The first catalog primarily consists of Fourier parameters for these stars, while the second catalog focuses on their photometric metallicity and distance estimates. Each catalog is available in machine-readable form in TXT format, with detailed information displayed in the file. Article Abstract Utilizing Zwicky Transient Facility (ZTF) data and existing RR Lyrae stars (RRLs) catalogs, this study achieves the first calibration of the $P-\phi_{31}-R_{21}-\text{[Fe/H]}$ and $P-\phi_{31}-A_{2}-A_{1}-\text{[Fe/H]}$ relations in the ZTF photometric system for RRab and RRc stars. We also re-calibrate the period-absolute magnitude-metallicity (PMZ) and period-Wesenheit-metallicity (PWZ) relations in the ZTF $gri$-bands for RRab and RRc stars. Based on nearly 4100 stars with precise measurements of $P$, $\phi_{31}$, $A_{2}$, and $A_{1}$, and available spectroscopic-metallicity estimates, the photometric-metallicity relations exhibit strong internal consistency across different bands, supporting the use of a weighted averaging method for the final estimates. The photometric-metallicity estimates of globular clusters based on RR Lyrae members also show excellent agreement with high-resolution spectroscopic measurements, with typical scatter of 0.15\,dex for RRab stars and 0.14\,dex for RRc stars, respectively. Using hundreds of local RRLs with newly derived photometric metallicities and precise Gaia Data Release 3 parallaxes, we establish the PMZ and PWZ relations in multiple bands. Validation with globular cluster RR Lyrae members reveals typical distance errors of 3.1% and 3.0% for the PMZ relations, and 3.1% and 2.6% for the PWZ relations for RRab and RRc stars, respectively. Compared to PMZ relations, the PWZ relations are tighter and almost unbiased, making them the recommended choice for distance calculations. We present a catalog of 73,795 RRLs with precise photometric metallicities; over 95% of them have accurate distance measurements. Compared to Gaia DR3, approximately 25,000 RRLs have precise photometric metallicities and distances derived for the first time.数据摘要 本部分为论文《基于兹威基瞬变设施（Zwicky Transient Facility, ZTF）的约7万颗天琴座RR型变星（RR Lyrae stars）测光金属丰度与距离估计》所提供的天琴座RR型变星参数星表。该论文包含两类核心星表：第一类星表主要收录该类天体的傅里叶参数，第二类星表则聚焦其测光金属丰度与距离估计结果。两类星表均以TXT格式提供机器可读文件，文件内包含详细的参数信息。 论文摘要 本研究利用兹威基瞬变设施（ZTF）的观测数据与已公开的天琴座RR型变星（RRLs）星表，首次在ZTF测光系统中，针对天琴座RRab型（RRab）与天琴座RRc型（RRc）变星完成了P-φ₃₁-R₂₁-[Fe/H]与P-φ₃₁-A₂-A₁-[Fe/H]关系的定标。同时，本研究还针对天琴座RRab与RRc型变星，在ZTF的g、r、i波段重新定标了周期-绝对星等-金属丰度（PMZ）与周期-韦森海特星等-金属丰度（PWZ）关系。 本研究基于近4100颗拥有精确P、φ₃₁、A₂、A₁测量值且具备光谱金属丰度估计结果的变星，发现不同波段下的测光金属丰度关系具有极强的内部一致性，这为采用加权平均法得到最终估计值提供了支撑。基于天琴座RR型变星成员星得到的球状星团测光金属丰度估计结果，与高分辨率光谱测量结果吻合极佳：天琴座RRab型变星的典型弥散为0.15 dex，RRc型则为0.14 dex。 本研究利用数百颗拥有新推导的测光金属丰度与精确盖亚第三版数据发布（Gaia Data Release 3, Gaia DR3）视差的本地天琴座RR型变星，建立了多波段下的PMZ与PWZ关系。通过球状星团内的天琴座RR型变星成员星进行验证，结果显示：针对天琴座RRab与RRc型变星，PMZ关系的典型距离误差分别为3.1%与3.0%，PWZ关系的典型距离误差则分别为3.1%与2.6%。相较于PMZ关系，PWZ关系的弥散更小且几乎无偏，因此推荐将其用于距离计算。 本研究公开了包含73795颗天琴座RR型变星的星表，这些天体均拥有精确的测光金属丰度，其中超过95%同时具备准确的距离测量结果。与Gaia DR3相比，约有25000颗天琴座RR型变星的测光金属丰度与距离参数为首次被精确推导得到。
