标题： On the Information Content of Stellar Spectra

摘要： 随着恒星振荡学观测质量的提高，减少模式参数估计中的随机误差和系统误差变得尤为重要。为此，理解振荡如何与直接可观测量（例如强度和光谱）以及派生量（例如多普勒速度）相关是至关重要的。在这里，我列出了一些我们需要考虑的影响，并展示其中一些影响的例子。 显示英文摘要

摘要： With the increasing quality of asteroseismic observations it is important to minimize the random and systematic errors in mode parameter estimates. To this end it is important to understand how the oscillations relate to the directly observed quantities, such as intensities and spectra, and to derived quantities, such as Doppler velocity. Here I list some of the effects we need to take into account and show an example of the impact of some of them.
