Pan-STARRS1 巡天正在收集赤纬-30°以北天空的多历元、多色观测，深度达到前所未有的程度。这些数据正在经过光度测量和天体测量校准，并将作为许多其他目的的参考。在本文中，我们介绍了 Pan-STARRS1 光度系统的测定：gP1、rP1、iP1、zP1、yP1 和 wP1。 Pan-STARRS1 光度测量系统基本上基于哈勃太空望远镜 Calspec 分光光度观测，而这些观测又基本上基于白矮星大气模型。我们定义了 Pan-STARRS1 星等系统，并详细描述了我们对系统通带的测量，包括仪器灵敏度和大气传输函数。还提供了副产品，包括向其他光度系统的转换、银河消光和恒星轨迹。我们最后讨论剩余的系统误差。
The Pan-STARRS1 survey is collecting multi-epoch, multi-color observations of the sky north of declination −30° to unprecedented depths. These data are being photometrically and astrometrically calibrated and will serve as a reference for many other purposes. In this paper, we present our determination of the Pan-STARRS1 photometric system: gP1, rP1, iP1, zP1, yP1, and wP1. The Pan-STARRS1 photometric system is fundamentally based on the Hubble Space Telescope Calspec spectrophotometric observations, which in turn are fundamentally based on models of white dwarf atmospheres. We define the Pan-STARRS1 magnitude system and describe in detail our measurement of the system passbands, including both the instrumental sensitivity and atmospheric transmission functions. By-products, including transformations to other photometric systems, Galactic extinction, and stellar locus, are also provided. We close with a discussion of remaining systematic errors.
