天赤道周围的UBVRI光度标准星：更新和增补
UBVRI Photometric Standard Stars Around the Celestial Equator: Updates and Additions
摘要：
在Johnson-Kron-Bronins测光系统上，对以天赤道为中心的202颗恒星进行了新的宽波段UBVRI光电观测。这些恒星是对先前公布的赤道测光标准星列表的更新和补充。该列表能够为两个天体半球提供一个围绕天空的内部一致的均匀宽带标准测光系统。当这些新的测量值与Landolt（1992）先前发表的测量值一起计算时，本文中的标准星的全部星等范围为8.90 < V < 16.30，色指数范围为-0.35 <（B-V）<+2.30。
英文摘要：
New broadband UBVRI photoelectric observations on the Johnson-Kron-Cousins photometric system have been made of 202 stars around the sky, and centered at the celestial equator. These stars constitute both an update of and additions to a previously published list of equatorial photometric standard stars. The list is capable of providing, for both celestial hemispheres, an internally consistent homogeneous broadband standard photometric system around the sky. When these new measurements are included with those previously published by Landolt (1992), the entire list of standard stars in this paper encompasses the magnitude range 8.90 < V < 16.30, and the color index range -0.35 < (B - V) < +2.30.
