我们描述了由Young、Milone和Stagg开发和讨论的新红外通带系统的新模拟和现场试验，他们讨论并说明了红外测光的状态，并提出了改进的方法。特别是，他们提出了一套新的通带，最大限度地减少了光度测定对大气窗口水蒸气带的依赖，这定义了许多以前的红外通带的边缘，特别是在它们没有设计的地点和条件下使用时。在本文中，我们给出了三种大气模式的数值模拟，展示了这些模式在新波段中的信噪比测量，并给出了在相对低海拔地区获得的观测数据。后者证明了该系统在大多数可以进行测光的天文地点的实用性，并允许将观测结果转换为该系统。
We describe new simulations and field trials of the new infrared passband system developed and discussed by Young, Milone, & Stagg, who discussed and illustrated the state of infrared photometry and suggested ways in which it could be improved. In particular, they presented a new set of passbands that minimize the dependence of the photometry on the water vapor bands of the atmospheric windows, which defined the edges of many previous infrared passbands, especially when used at sites and under conditions for which they were not designed. In this paper, we present numerical simulations for three atmospheric models, demonstrate a measure of the signal‐to‐noise ratio in the new passbands for these models, and present observational data obtained at a relatively low‐elevation site. The latter demonstrate the utility of this system for most astronomical sites where photometry can be performed, and permit the transformation of observations to this system.
