Abstract

This article presents new astronomical source catalogs using data from the BUFFALO Survey. These catalogs contain detailed information for over 100,000 astronomical sources in the six BUFFALO clusters: A370, A2744, AS1063, MACS 0416, MACS 0717, and MACS 1149 spanning a total of 240 arcmin2. The catalogs include positions and forced photometry measurements of these objects in the F275W, F336W, F435W, F606W, F814W, F105W, F125W, F140W, and F160W HST bands, Keck-NIRC2/VLT-HAWKI Ks band, and IRAC Channel 1 and 2 bands. Additionally, we include photometry measurements in the F475W, F625W, and F110W bands for A370. This catalog also includes photometric redshift estimates computed via template fitting using LePhare. When comparing to a spectroscopic reference, we obtain an outlier fraction of 8.6% and scatter, normalized median absolute deviation, of 0.059. The catalogs are publicly available for their use by the community (https://archive.stsci.edu/hlsp/buffalo/).

BUFFALO巡天观测场的自洽组合 HST、K 波段和 Spitzer 测光目录

这篇文章介绍了利用 BUFFALO 巡天数据编制的新天文源星表。这些星表包含了六个 BUFFALO 星团中超过 100,000 个天文源的详细信息：A370、A2744、AS1063、MACS 0416、MACS 0717 和 MACS 1149，总跨度为 240 弧分2。星表包括这些天体在 F275W、F336W、F435W、F606W、F814W、F105W、F125W、F140W 和 F160W HST 波段、Keck-NIRC2/VLT-HAWKI Ks 波段以及 IRAC Channel 1 和 2 波段的位置和强制测光数据。此外，我们还包括 A370 在 F475W、F625W 和 F110W 波段的测光数据。这个星表还包括通过使用 LePhare 进行模板拟合计算得出的测光红移估计值。在与光谱参照物进行比较时，我们得到的离群点比例为 8.6%，散度（归一化中位绝对偏差）为 0.059。这些星表都是公开的，可供社会各界使用（https://archive.stsci.edu/hlsp/buffalo/）。
