George Helffrich; Erratum to Extended-Time Multitaper Frequency Domain Cross-Correlation Receiver-Function Estimation. Bulletin of the Seismological Society of America ; 98 (3): 1608. doi: https://doi.org/10.1785/0120080022
In my article, “Extended-Time Multitaper Frequency Domain Cross-Correlation Receiver-Function Estimation” (Helffrich, 2006), I discovered an error transcribing the algorithm from code to its English-language description. The window overlap is 75%, not 50% as originally reported. A corrected version of Figure 1 and its caption appears here to illustrate the method.
I thank Takuo Shibutani for bringing the problem to my attention.
