摘要:

我们描述了泛星移动物体处理系统(MOPS),一个现代化的软件包,产生自动小行星的发现和识别从下一代天文测量望远镜的瞬态检测目录。MOPS在从合成但真实的小行星群产生轨道方面的效率达到99.5%以上,这些小行星的测量是由Pan-STARRS 4级望远镜模拟的。此外,使用非物理网格人口,我们表明,MOPS可以检测人口目前未知的对象,如星际小行星。MOPS已成功地适应原型Pan-STARRS 1望远镜,尽管预期的错误检测率,填充因子损失和相对稀疏的观测节奏相比,一个假设的Pan-STARRS 4望远镜和调查的差异。MOPS在一个晚上探测物体的效率仍然超过99.5%,但在多个晚上探测到的物体的轨道效率下降到80%。这一损失主要是由于可配置的MOPS处理限制,这些限制尚未针对Pan-STARRS 1任务进行调整。MOPS核心软件包是15个多人年软件开发的产物,并在第三方软件中纳入了无数年的额外努力,以执行空间搜索或轨道确定等较低级别的功能。我们描述了高层次的设计MOPS和必要的子组件,适合MOPS的其他调查计划,并建议未来MOPS的发展路线图。

英文摘要:

We describe the Pan-STARRS Moving Object Processing System (MOPS), a modern software package that produces automatic asteroid discoveries and identifications from catalogs of transient detections from next-generation astronomical survey telescopes. MOPS achieves > 99.5% efficiency in producing orbits from a synthetic but realistic population of asteroids whose measurements were simulated for a Pan-STARRS4-class telescope. Additionally, using a non-physical grid population, we demonstrate that MOPS can detect populations of currently unknown objects such as interstellar asteroids. MOPS has been adapted successfully to the prototype Pan-STARRS1 telescope despite differences in expected false detection rates, fill-factor loss and relatively sparse observing cadence compared to a hypothetical Pan-STARRS4 telescope and survey. MOPS remains >99.5% efficient at detecting objects on a single night but drops to 80% efficiency at producing orbits for objects detected on multiple nights. This loss is primarily due to configurable MOPS processing limits that are not yet tuned for the Pan-STARRS1 mission. The core MOPS software package is the product of more than 15 person-years of software development and incorporates countless additional years of effort in third-party software to perform lower-level functions such as spatial searching or orbit determination. We describe the high-level design of MOPS and essential subcomponents, the suitability of MOPS for other survey programs, and suggest a road map for future MOPS development.
