开普勒使命任务将为许多恒星提供大的分离。开普勒Asteroseismic财团的任务之一是确定所观察到的恒星的半径，从大的分离和其他编目的“经典”的数据，如有效温度，金属丰度，亮度，距离等，我们提出了一个详细的分析结果的误差在半径估计所造成的输入参数的错误。这项工作使我们能够确定哪些参数将受益于对有趣病例的后续观察。
The Kepler mission will provide large separations for many stars. One of the tasks of Kepler Asteroseismic Consortium is to determine radii of the observed stars from the large separations and other catalogued “classical” data such as effective temperature, metallicities, brightness, distance etc. We present the results of a detailed analysis of errors in the radius estimates caused by errors in the input parameters. This exercise enables us to determine which parameters will benefit from follow-up observations of the interesting cases.
