论文摘要
光谱仪器和校准方法的最新进展极大地提高了类星体光谱的质量。超级计算机计算表明，在高光谱分辨率下，在先前对基本常数的时空变化的某些分析中使用的程序可能会产生伪造的测量，并系统地偏向于无效结果。还总结了分析方法中的发展，并给出了用于分析新数据和即将出现的数据的处方。
Recent advances in spectroscopic instrumentation and calibration methods dramatically improve the quality of quasar spectra. Supercomputer calculations show that, at high spectral resolution, procedures used in some previous analyses of spacetime variations of fundamental constants are likely to generate spurious measurements, biased systematically towards a null result. Developments in analysis methods are also summarised and a prescription given for the analysis of new and forthcoming data.
