分光偏振测量和磁记录诊断
Diagnostics for spectropolarimetry and magnetography
摘要：
对现代分光偏振仪和磁力仪的能力进行评估是有必要的，因为我们的大多数天体物理结果依赖于仪器的准确性和观测值对所寻求的物理参数变化的敏感性。这种评估的贡献将在本次演讲中，重点将是使用所谓的响应函数来衡量探测能力的谱线和分析方法来估计的不确定性，在仪器的影响方面的结果。成像磁力仪实验（IMaX）和偏振和日震成像仪（PHI）将被用作研究案例。
英文摘要：
An assessment on the capabilities of modern spectropolarimeters and magnetographs is in order since most of our astrophysical results rely upon the accuracy of the instrumentation and on the sensitivity of the observables to variations of the sought physical parameters. A contribution to such an assessment will be presented in this talk where emphasis will be made on the use of the so-called response functions to gauge the probing capabilities of spectral lines and on an analytical approach to estimate the uncertainties in the results in terms of instrumental effects. The Imaging Magnetograph eXperiment (IMaX) and the Polarimetric and Helioseismic Imager (PHI) will be used as study cases.
